Architecture Overview

The relayer sits between Etherlink dApps and the Tezos L1, acting as a translation layer that maps EVM calls to Tezos operations.

Tezos X Relayer architecture diagram

Component	Role
RelayerProvider	Implements `EIP1193Provider`, handles all `window.ethereum` calls
BeaconClient	Connects to Temple wallet via Beacon SDK
TezlinkClient	Sends operations to Tezos L1 via Tezlink RPC
GatewayBuilder	Builds Micheline calldata for the NAC gateway
EIP-6963 announcer	Broadcasts provider info for modern dApp wallet pickers

Every tz1 address has a deterministic EVM alias:

tz1 → SHA3(prefix + tz1_bytes) → 0xAlias

This alias is computed by the Tezlink RPC via tez_getEthereumTezosAddress and used as the account returned by eth_requestAccounts.
