Wallet Modules Overview
Explore WDK wallet modules for building self-custodial wallets across supported chains.
The Wallet Development Kit (WDK) provides a set of modules that support multiple blockchain networks. All modules share a common interface, ensuring consistent behavior across different blockchain implementations.
Shared Fee Limits
Wallet modules can expose fee caps through their configuration objects. Use the chain-specific docs for exact units and supported operations.
| Option | Applies to | Description |
|---|---|---|
transferMaxFee | transfer() | Caps token transfer fees in the module's base fee unit. |
transactionMaxFee | sendTransaction() and signTransaction() | Caps native transaction send/sign flows separately from token transfers when the module supports that base wallet option. |
Supported Networks
This package works with multiple blockchain networks through wallet registration.

Bitcoin Mainnet

Ethereum, Sepolia Testnet, L2s, etc.

Tron Mainnet

TON Mainnet

Solana Mainnet


Spark Mainnet
