Conclusion
The primary purpose of the Wormhole protocol is to address the interoperability challenges inherent in the fragmented blockchain ecosystem.
By providing a standardized framework Wormhole enables developers to build decentralized applications (DApps) that transcend the limitations of individual blockchains.
Going straight to the point. Let’s, dive into wormhole.
What Exactly is Wormhole?
Wormhole serves as a versatile and adaptable message-passing protocol, facilitating seamless communication between distinct blockchains. By providing a straightforward mechanism for transmitting messages across blockchain networks, Wormhole empowers both developers and users to harness the strengths and opportunities presented by diverse ecosystems.
For developers, Wormhole offers a practical solution to the challenge of interoperability between blockchains. Through this protocol, developers can create cross-chain applications that capitalize on the unique features and functionalities of different blockchain networks.
Moreover, Wormhole extends its benefits beyond developers to users of cross-chain applications. By enabling communication between blockchains, Wormhole allows users to access and interact with a broader range of blockchain-based services and assets.
I recommend you watch this introductory video about Wormhole ⤵
Moving forward, I want to clarify something,
Wormhole isn't a blockchain itself; it acts as a communication route between many different blockchains and rollups.
Although it facilitates cross-chain communication, it's not precisely a token bridge. Instead, protocols built on Wormhole handle this task.
So, why do you need Wormhole? is it that important?
Here are some key benefits that Wormhole offers for your Cross-chain Decentralized Applications (xDapps):
1. Reach Users Across Blockchains: With Wormhole, xDapps can interact with users on different blockchains, expanding your reach and fostering collaboration.
2. Unified Liquidity: Wormhole creates xAssets, which can be seamlessly transferred across blockchains, consolidating liquidity and simplifying fundraising for projects.
3. Decentralized Infrastructure: Wormhole is decentralized from the outset, giving users more control over their assets and reducing reliance on centralized exchanges or bridges.
4. Enhanced Performance: xDapps can leverage the strengths of various blockchains to optimize tasks, accelerate transactions, and enhance data storage, resulting in improved performance.
5. Access to a Larger Market: xAssets can move seamlessly within the ecosystem, enabling listing on multiple exchanges and secure storage on any blockchain, broadening accessibility for projects and users.
6. Easy Integration and Collaboration: xDapps within the Wormhole ecosystem can integrate effortlessly, fostering collaboration among smart contracts and enabling the development of complex decentralized solutions.
7. Future-proofing Your Dapp: Wormhole is designed to evolve with the decentralized ecosystem, ensuring sustainability and support for future advancements in blockchain technology, making it an excellent choice for forward-thinking developers.
I am no fortune teller 😄, but I can see that this benefit is exactly what you as a developer need.
Now, how does Bridging work? What does wormhole rely on
Wormhole relies on two key processes, Attest and Transfer, to bridge tokens across different blockchains. These processes are crucial for ensuring smooth token transfers while preserving their attributes and functionalities.
Let's delve into each process to gain a clear understanding of how Wormhole achieves seamless token bridging. ⤵
Attestation
Attestation involves 'registering' a token with the token bridge.
Before being transferred, tokens must first be attested on their Origin Chain and have corresponding wrapped tokens created on the Foreign Chain.
Attesting on the Origin Chain creates requisite addresses and metadata that allow the wrapped asset to exist on Foreign Chains.
Transfer
Once attested, tokens are mapped from their Native Chain to 'wrapped' assets on the Foreign Chains. For example, transferring an Ethereum-native token to Solana results in a 'wrapped asset' on Solana. Transferring the same asset back to Ethereum restores the native token.
Ok, imagine you have Ethereum ($ETH) on the Ethereum mainnet, but you want to use it on the Solana mainnet instead.
First, certain addresses and details are set up on the Ethereum mainnet, allowing your $ETH to exist on Solana. Then, Wrapped Ether ($wETH) is created on the Solana mainnet, matching the value of your $ETH on Ethereum. (This is the Attestation step)
Your $ETH on Ethereum is then locked, and an equal amount of $wETH tokens are minted on Solana. These $wETH tokens can be freely used like any other token on the Solana network. (This is the Transfer process)
If you ever want to switch your $wETH tokens back to ETH on Ethereum, simply burn your $wETH tokens on Solana, and the equivalent amount of $ETH tokens on Ethereum will be unlocked.
Let me show you a code examples on how the attestation process works from Solana to Ethereum. ⤵
// Submit transaction - results in a Wormhole message being published
const transaction = await attestFromSolana(
connection,
SOL_BRIDGE_ADDRESS,
SOL_TOKEN_BRIDGE_ADDRESS,
payerAddress,
mintAddress
);
const signed = await wallet.signTransaction(transaction);
const txid = await connection.sendRawTransaction(signed.serialize());
await connection.confirmTransaction(txid);
// Get the sequence number and emitter address required to fetch the signedVAA of our message
const info = await connection.getTransaction(txid);
const sequence = parseSequenceFromLogSolana(info);
const emitterAddress = await getEmitterAddressSolana(SOL_TOKEN_BRIDGE_ADDRESS);
// Fetch the signedVAA from the Wormhole Network (this may require retries while you wait for confirmation)
const { signedVAA } = await getSignedVAA(
WORMHOLE_RPC_HOST,
CHAIN_ID_SOLANA,
emitterAddress,
sequence
);
// Create the wrapped token on Ethereum
await createWrappedOnEth(ETH_TOKEN_BRIDGE_ADDRESS, signer, signedVAA);
Now, here is how you attest from Ethereum to Solana:
// Submit transaction - results in a Wormhole message being published
const receipt = await attestFromEth(
ETH_TOKEN_BRIDGE_ADDRESS,
signer,
tokenAddress
);
// Get the sequence number and emitter address required to fetch the signedVAA of our message
const sequence = parseSequenceFromLogEth(receipt, ETH_BRIDGE_ADDRESS);
const emitterAddress = getEmitterAddressEth(ETH_TOKEN_BRIDGE_ADDRESS);
// Fetch the signedVAA from the Wormhole Network (this may require retries while you wait for confirmation)
const { signedVAA } = await getSignedVAA(
WORMHOLE_RPC_HOST,
CHAIN_ID_ETH,
emitterAddress,
sequence
);
// On Solana, we have to post the signedVAA ourselves
await postVaaSolana(
connection,
wallet,
SOL_BRIDGE_ADDRESS,
payerAddress,
signedVAA
);
// Finally, create the wrapped token
const transaction = await createWrappedOnSolana(
connection,
SOL_BRIDGE_ADDRESS,
SOL_TOKEN_BRIDGE_ADDRESS,
payerAddress,
signedVAA
);
const signed = await wallet.signTransaction(transaction);
const txid = await connection.sendRawTransaction(signed.serialize());
await connection.confirmTransaction(txid);
Moving to transfer, here is how you transfer from Solana to Ethereum
// Submit transaction - results in a Wormhole message being published
const transaction = await transferFromSolana(
connection,
SOL_BRIDGE_ADDRESS,
SOL_TOKEN_BRIDGE_ADDRESS,
payerAddress,
fromAddress,
mintAddress,
amount,
targetAddress,
CHAIN_ID_ETH,
originAddress,
originChain
);
const signed = await wallet.signTransaction(transaction);
const txid = await connection.sendRawTransaction(signed.serialize());
await connection.confirmTransaction(txid);
// Get the sequence number and emitter address required to fetch the signedVAA of our message
const info = await connection.getTransaction(txid);
const sequence = parseSequenceFromLogSolana(info);
const emitterAddress = await getEmitterAddressSolana(SOL_TOKEN_BRIDGE_ADDRESS);
// Fetch the signedVAA from the Wormhole Network (this may require retries while you wait for confirmation)
const { signedVAA } = await getSignedVAA(
WORMHOLE_RPC_HOST,
CHAIN_ID_SOLANA,
emitterAddress,
sequence
);
// Redeem on Ethereum
await redeemOnEth(ETH_TOKEN_BRIDGE_ADDRESS, signer, signedVAA);
And here is how you transfer from Ethereum to Solana:
// determine destination address - an associated token account
const solanaMintKey = new PublicKey(
(await getForeignAssetSolana(
connection,
SOLANA_TOKEN_BRIDGE_ADDRESS,
CHAIN_ID_ETH,
hexToUint8Array(nativeToHexString(tokenAddress, CHAIN_ID_ETH) || "")
)) || ""
);
const recipientAddress = await Token.getAssociatedTokenAddress(
ASSOCIATED_TOKEN_PROGRAM_ID,
TOKEN_PROGRAM_ID,
solanaMintKey,
walletAddress
);
// Submit transaction - results in a Wormhole message being published
const receipt = await transferFromEth(
ETH_TOKEN_BRIDGE_ADDRESS,
signer,
tokenAddress,
amount,
CHAIN_ID_SOLANA,
recipientAddress
);
// Get the sequence number and emitter address required to fetch the signedVAA of our message
const sequence = parseSequenceFromLogEth(receipt, ETH_BRIDGE_ADDRESS);
const emitterAddress = getEmitterAddressEth(ETH_TOKEN_BRIDGE_ADDRESS);
// Fetch the signedVAA from the Wormhole Network (this may require retries while you wait for confirmation)
const { signedVAA } = await getSignedVAA(
WORMHOLE_RPC_HOST,
CHAIN_ID_ETH,
emitterAddress,
sequence
);
// On Solana, we have to post the signedVAA ourselves
await postVaaSolana(
connection,
wallet,
SOL_BRIDGE_ADDRESS,
payerAddress,
signedVAA
);
// Finally, redeem on Solana
const transaction = await redeemOnSolana(
connection,
SOL_BRIDGE_ADDRESS,
SOL_TOKEN_BRIDGE_ADDRESS,
payerAddress,
signedVAA,
isSolanaNative,
mintAddress
);
const signed = await wallet.signTransaction(transaction);
const txid = await connection.sendRawTransaction(signed.serialize());
await connection.confirmTransaction(txid);
Diving into the Wormhole Architecture
Moving on, I want to break down the wormhole architecture is in a very simple way 😉
Now, Wormhole has two main parts: on-chain and off-chain.
The on-chain part manages transactions directly on the blockchain, while the off-chain part works alongside it.
Together, they allow for smooth cross-chain communication and transactions between different blockchains, making it easier for decentralized applications and financial activities to operate across networks.
On-Chain Components:
Emitter contracts are essential for cross-chain communication in Wormhole. They kickstart message transfers between blockchains by calling the publish message method on the Core Contract, which records important details like the emitter's identity and message sequence number in Transaction Logs.
Types of emitter contracts in Wormhole include:
1. xAsset Contracts: These convert regular tokens into xAssets compatible with Wormhole for smooth cross-chain transfers.
2. Relay Contracts: They connect cross-chain applications with specific blockchains through a decentralized Generic Relayer network.
3. Gas Oracles (in progress): These offer fair gas prices for efficient transaction processing.
4. Worm Router Contracts: They enable DApps to become cross-chain, accessible to users on any Wormhole-supported blockchain through client-side code.
5. Wormhole Core Contract: This central contract oversees cross-chain communication, monitored by Guardians ensuring network integrity. It processes messages and fosters interoperability between blockchains.
6. Transaction Logs: Each blockchain has its own logs, crucial for Guardians to monitor messages emitted by the Core Contract. They ensure transparency and accountability, tracking cross-chain transactions for Wormhole's security.
Here is the image breakdown of what the on-chain and off-chain contains ⤵
Off-chain Components
1. Guardian Network: Made up of validators, the Guardian Network oversees Core Contracts on supported chains, bolstering Wormhole's security. With 19 Guardians in total, popular ones include Everstake, 01node, ChainLayer, and Certus One.
2. Worm Router Contracts (in development): These contracts enable Dapps to become xDapps, promoting cross-chain compatibility and expanding their user base.
3. Specialized Relayers: These relayers manage VAAs (Verified Action Authorities) for specific protocols or xDapps, executing custom logic off-chain to improve cross-chain compatibility.
4. Generic Relayers (In development): This decentralized relayer network aids in delivering on-chain requested messages through the Wormhole Relay Contract, boosting interoperability.
5. Wormchain (In development): A dedicated cosmos blockchain supporting the Guardian Network, ensuring seamless cross-chain communication and secure operations within Wormhole.
6. API: Serving as a REST server, the API grants access to VAA or Guardian Network details, offering developers and users an easy way to access information on cross-chain transactions and network governance.
7. Verifiable Action Approvals (VAAs): VAAs are key components in Wormhole, containing messages from cross-chain xDapps. Each VAA carries emitting contract information, ensuring network transparency. Guardians validate VAAs by signing them, requiring 13 out of 19 signatures for authentication, ensuring secure and trustworthy cross-chain transactions.
The Wormhole SDK
The Wormhole SDK (Software Development Kit) serves as a comprehensive suite of tools, libraries, and documentation meticulously crafted by Wormhole.
This SDK offers tools for interacting with Wormhole smart contracts on supported blockchains. Developers can use these contracts to send messages containing details like the originating blockchain, address, data consistency level, timestamp, unique message sequence number, and payload.
When a Wormhole contract processes a transaction message, Guardians monitor the process. Once the transaction reaches the specified confirmation time on the originating blockchain, Guardians create a Signed Verifiable Action Approval (SignedVAA).
Verifiable Action Approvals (VAAs) are central to Wormhole's ecosystem, containing notifications from xDapps and originating contract information.
