Multichain Architecture - Compose.Market

Compose.Market runs fully multichain: Solidity contracts on multiple EVM chains and native programs on Solana. On EVM, users get the same Smart Account address across all supported chains through deterministic CREATE2 deployment.

Cross-Chain Identity

How It Works

The Smart Account address is derived from:

address = CREATE2(factory, keccak256(admin, salt), initCodeHash)

Since we deploy the same AccountFactory at the same address on all chains, users automatically get identical Smart Account addresses.

Component	Requirement	Address
AccountFactory	Universal	`0x4bE0ddfebcA9A5A4a617dee4DeCe99E7c862dceb`
EntryPoint v0.7	Universal	`0x0000000071727De22E5E9d8BAf0edAc6f37da032`
Account Implementation	Chain-specific	Varies per chain
Paymaster	Chain-specific	Varies per chain

Supported Chains

Networks are identified across the platform by their CAIP-2 networkId (eip155:* for EVM, solana:* for SVM) — the same identifier the SDK and APIs take.

Chain	Network ID (CAIP-2)
Avalanche Mainnet	`eip155:43114`
Sei Mainnet	`eip155:1329`
Arc Testnet	`eip155:5042002`
Solana Devnet	`solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1`
