a well typed sdk for web3

0.1.1

manifold-sdk
a human web3 interface
SDK Overview:
- Keep your private keys in your client, safe and sound
- Import and export JSON wallets
- Import and export BIP 39 mnemonic phrases (12-word backup phrases) and HD wallets (English, Italian, Japanese, Korean, Simplified Chinese, Traditional Chinese)
- Connect to Ethereum nodes over
JSON-RPC(both public and private). - Aliases names are first-class citizens; it can be used to log in any Manifold Finance services
- Complete functionality for all your Manifold Finance needs
- Large collection of test cases which are maintained and added to
- Fully TypeScript-ready, with definition files and full TypeScript source
