"detailedDescription": "# Crosschain transfer flow\n\nThe user initiates a transfer (sometimes called an intent) by depositing into the local chain \"SpokePool\" contract. The deposit specifies the recipient, the destination chain, the amount, the input token, the output token, a fill deadline by which the destination chain transfer must complete, and an optional exclusivity window during which only a chosen relayer can fill. User funds remain in the SpokePool; the deposit's parameters are not persisted in contract storage but only captured in a FundsDeposited event log, which relayers index offchain to learn about deposits.\n\nRelayers fill a crosschain request by calling the destination chain's SpokePool. During the exclusivity window only the chosen relayer can fill; after it expires anyone can. No fill is accepted past the fill deadline. Funds go to the user and the relay hash is marked Filled in the SpokePool's fillStatuses mapping to prevent double-fills.\n\n# Relayer repayments\n\nWhen a crosschain transfer is fulfilled, the relayer specifies on which chain and to which address they want to be repaid. A whitelisted proposer periodically posts a \"root bundle\" to the HubPool containing how much the protocol owes to each relayer (relayer refunds) and the pool rebalances needed so that there is enough liquidity on each chain for the refunds to be paid. The correctness of these roots is crucial; otherwise relayers could lie about filling a transfer and capture user funds.\n\nRoot bundles settle in two levels:\n\n1. Optimistic (Across-native): the proposer bonds 0.45 ABT (a simple ETH wrapper, not to be confused with the ACX governance token) and the root sits in a challenge period of 30m. If unchallenged, the bundle executes; UMA is not involved in this happy path.\n2. Dispute escalation (UMA): anyone can call disputeRootBundle() within the challenge period by posting an equal counter-bond. The disputed bundle is discarded immediately so a new proposal can be submitted, while the dispute itself is escalated to UMA's optimistic oracle, which resolves via UMA token voting; the losing party loses their bond.\n\nFor chains with a canonical L1 to L2 messenger, tokens and admin / refund messages move from the HubPool to each SpokePool through that chain's canonical bridge via a per-chain adapter. For chains without one (BNB Smart Chain, HyperEVM, Plasma, Tempo, Tron, ...), Across uses universal adapters: the HubPool writes the message calldata into the HubPoolStore on Ethereum, and the destination chain reads it by verifying a storage proof against Ethereum's state through a light client contract on the destination. Tokens travel via LayerZero OFT, or via Circle CCTP for USDC.\n\nLPs can provide single-token liquidity to the HubPool to front relayer refunds across chains, earning yield from an LP fee captured on every transfer.",

"detailedDescription": "# Architecture\nThe Wormhole messaging protocol consists of a `WormholeCore` contract on each supported chain. Application contracts like the Token Bridge, the multichain token framework *NTT* ('native token transfers') and the Mayan intent framework contracts are each connected to it. The token bridge is a lock-minting token bridge, NTT is a customizable multichain token framework and Mayan supports stablecoin transfers and crosschain asset swaps of any kind as an intent protocol.\n\n# Crosschain oracle and validation\nWormhole uses the same validators for its core messaging protocol on all supported chains. They are called *guardians* and validate crosschain messages with a 13/19 threshold. Guardians are external validator companies who are expected to run their own nodes of all chains they validate on, but they also delegate the running of full nodes to others for smaller chains.\n\n# Upgradeability\nThe core protocol and token bridge contracts are upgradeable by the same *guardians* who validate crosschain messages. Application-level contracts can have custom upgradeability.\n\n# Monitoring\nWormhole provides a [block explorer](https://wormholescan.io/) which is mostly intended for users and researchers tracking crosschain transactions and for aggregate metrics. As for [security and monitoring tools](https://wormhole-foundation.github.io/wormhole-dashboard/#/?endpoint=Mainnet), Wormhole offers *Governor* a global token flow monitoring layer that Guardians can use to identify suspicious transfers before signing them. *Global Accountant* tracks the circulating supply of *WTT* and *NTT* assets on all chains and alerts Guardians if a transaction would increase the supply.",

"description": "Intent-based centralized EOA bridge optimised for speed, multichain and multiasset support.",
"detailedDescription": "# Architecture\nRelay is an intent-based, non-minting bridge. A user requests a route from the [Relay API](https://docs.relay.link/references/api/api_guides/bridging-integration-guide) and deposits their funds to simple smart contract or EOA on the source chain, and a solver fronts liquidity on the destination chain before settling back against the user's source-side payment. The destination transaction is a regular transfer, swap, or contract call made by the solver from their own pre-positioned liquidity.\n\nAfter a solver fills the user on the destination chain, the solver asks the centralized Relay Oracle to verify the source payment and destination fill. The Oracle reads chain data offchain and returns an attestation. The solver submits that attestation to the `RelayOracle` on the Relay Chain, which updates the `RelayHub`: the deposit is represented as Hub balance and that balance is transferred to the solver. Solvers then withdraw accumulated Hub balances through the `Allocator`, which produces a signed withdrawal payload accepted by the target-chain `Depository.execute(CallRequest, signature)`.\n\n# Crosschain oracle and validation\nThe destination-chain user outcome depends on the solver filling correctly and quickly, while settlement depends on Relay's centralized Oracle. Incorrect attestations can misattribute balances on the Hub and steal funds. The 'Allocator', which is the signing part of the relay oracle, uses the MPC signing framework on the NEAR blockchain.\n\n# Refunds\nThere are no onchain mechanisms for refunds, making them fully depend on the good will of solvers and the relay admins.\n\n# Monitoring\nRelay provides an [explorer](https://relay.link/transactions) and an [API](https://docs.relay.link/references/api/overview) to monitor transactions. There is a sovereign rollup on Celestia called 'relay chain' that acts as a ledger for the protocol's crosschain accounting.",
