• ethereum:1 -> polkadot:2034 with USDC

• ethereum:1 -> polkadot:2043 with TRAC

• ethereum:1 -> polkadot:3369 with MYTH

Polkadot -> Ethereum

Examples covered:

• polkadot:1000 -> ethereum:1 with DOT

• ethereum_l2:8453 -> polkadot:1000 with USDC

Polkadot -> L2

Examples covered:

• polkadot:1000 -> ethereum_l2:42161 with WETH

• polkadot:1000 -> ethereum_l2:8453 with USDC

Inter-Parachain

Examples covered:

• polkadot:1000 -> polkadot:2034 with USDC

• polkadot:2034 -> polkadot:1000 with USDC

Registration

Examples covered:

• Agent creation with api.createAgent()

• Token registration with api.registerToken()

Common SDK Pattern

Most route cases follow the same pattern:

const sender = api.sender(from, to)
const transfer = await sender.build(
    sourceAccount,
    beneficiaryAccount,
    tokenAddress,
    amount,
    options,
)

The returned transfer.tx can then be submitted to the wallet by your application.
