Chains & Contracts

Every chain Mayan supports, with the identifiers you pass to the API and the contracts you interact with.

Chains are identified by their Wormhole chain ID, not their EVM chain ID. Base is 30, not 8453. Passing an EVM chain ID where a Wormhole chain ID is expected will be rejected or produce the wrong result.

Supported chains

Chain	Name in API	Wormhole chain ID	EVM chain ID
Solana	`solana`	1	n/a
Ethereum	`ethereum`	2	1
BNB Smart Chain	`bsc`	4	56
Polygon	`polygon`	5	137
Avalanche	`avalanche`	6	43114
Sui	`sui`	21	n/a
Arbitrum	`arbitrum`	23	42161
Optimism	`optimism`	24	10
Base	`base`	30	8453
Linea	`linea`	38	59144
Unichain	`unichain`	44	130
HyperEVM	`hyperevm`	47	999
Monad	`monad`	48	143
Fogo	`fogo`	51	n/a
HyperCore	`hypercore`	65000	n/a

Support differs by direction. GET https://sia.mayan.finance/v10/init returns the live list with originActive and destinationActive per chain. Read it rather than assuming a chain works both ways.

EVM contracts

The Forwarder is the single entry point for EVM swaps, and is deployed at the same address on every supported EVM chain.

Contract	Address
Mayan Forwarder	`0x337685fdaB40D39bd02028545a4FfA7D287cC3E2`

Approve the Forwarder for ERC20 inputs before swapping. See Forwarder Contract.

API endpoints

Service	URL
Quote API	`https://price-api.mayan.finance/v3`
Explorer API	`https://explorer-api.mayan.finance/v3`
Chain and token config	`https://sia.mayan.finance/v10/init`

Tokens

Any token with a contract address is routable. GET https://price-api.mayan.finance/v3/tokens?chain=solana returns the whitelisted list for a chain, and dropping the chain parameter returns every chain.

Verifying addresses

Every address on this page is exported by the SDK as addresses, so you can read them at runtime rather than hardcoding:

import { addresses } from "@mayanfinance/swap-sdk";

console.log(addresses.MAYAN_FORWARDER_CONTRACT);

All contracts are public and audited. See Security & Audits.
