LedgerKit

LedgerKit.dev is a browser-based tool designed to help users and developers manage their Ledger assets in one place — no app downloads required.

With LedgerKit.dev, users can:

Send & receive tokens across supported blockchains.

Experience clear signing firsthand, understanding how secure transaction approval works with their Ledger device.

Explore ERC-7730 features, including generating formats and browsing pull requests related to the standard. The ERC-7730 registry dashboard lets users search, filter, and check merged PRs, closed PRS etc to better understand the proposal lifecycle.

For developers, LedgerKit.dev is also a day-to-day testing playground:

Experiment with signing and integration flows.

Test transactions safely without extra setup.

Leverage the ERC-7730 registry to build and learn from real proposals.

🌐 Supported Chains

LedgerKit.dev currently supports 5 EVM chains (mainnet + testnet):

Ethereum (Mainnet + Sepolia)

Polygon

Base

Optimism

Arbitrum

Additionally, Sui SDK integration is in active development, opening up multi-chain experimentation beyond EVM.
