Supported Chains

note

SDK also supports EVM localnets and bitcoin regtest. This is possible with merry, a complete localnet environment setup for testing the Garden systems. If Merry is not running, whenever you pass localnets to the SDK, it will throw an error saying unsupported asset.

Garden supports the following chains:

  • Bitcoin
  • Ethereum
  • Arbitrum

We use WBTC as the base asset for EVM-based chains.

The following swaps are supported:

  • BTC to WBTC (Bitcoin -> Ethereum)
  • WBTC to WBTC (Ethereum -> Arbitrum)
note

From chain and to chain are interchangeable here.

How do I get the supported chains?​

@gardenfi/orderbook exports a constant called Chains which contains all supported chains.

import { Chains } from '@gardenfi/orderbook';

const bitcoin = Chains.bitcoin;
const ethereum = Chains.ethereum;
const arbitrum = Chains.ethereum_arbitrum;

How do I specify an asset on the X chain?​

@gardenfi/orderbook exports a constant called Assets which contains respective chains and it's supported assets.

import { Assets } from '@gardenfi/orderbook';

const wbtcOnEthereum = Assets.ethereum.WBTC;
const wbtcOnArbitrum = Assets.ethereum_arbitrum.WBTC;
const btc = Assets.bitcoin.BTC;

Now, these can be passed to swap() gardenJS to perform swaps. Checkout swap example in Swapping from BTC to WBTC.

Contracts​

Garden uses the following contracts to perform swaps on respective chains:
