Networks

Network	Network Type	Features
Ethereum & EVM	`NETWORK_TYPE_EVM`	Native tokens, ERC-20, ERC-721, custom contract calls and deployment, message and typed-data signing
Bitcoin	`NETWORK_TYPE_BITCOIN`	Native BTC
Solana	`NETWORK_TYPE_SOLANA`	Native SOL, SPL tokens, custom program transactions, message signing
Stellar	`NETWORK_TYPE_STELLAR`	Native XLM, issued assets, trustlines, custom Classic transactions and Soroban contract interactions
Sui	`NETWORK_TYPE_SUI`	Native SUI, Coins, custom Move calls and programmable transaction blocks, message signing
TON	`NETWORK_TYPE_TON`	Native GRAM (prev. TON), Jettons, custom contract messages, message signing
Aptos	`NETWORK_TYPE_APTOS`	Native APT, Coins, custom Move entry-function calls, message signing
TRON	`NETWORK_TYPE_TRON`	TRX, TRC-10, TRC-20
Movement	`NETWORK_TYPE_APTOS`	Native MOVE, Coins, custom Move entry-function calls
Sonic SVM	`NETWORK_TYPE_SOLANA`	Native SOL, SPL tokens, custom program transactions

Aptos / Movement use NETWORK_TYPE_APTOS and the same transaction payloads. Mainnet chainId: "1" for Aptos, "126" for Movement.
Solana / Sonic SVM use NETWORK_TYPE_SOLANA. Select the network with solanaSend* or sonicSvmSend*, respectively; these payloads ignore chainId.

Chain ID	Network
`1`	Ethereum
`137`	Polygon
`56`	BNB Smart Chain
`42161`	Arbitrum One
`10`	Optimism
`8453`	Base
