Wrapped CHI (WCHI) is an ERC-20 token on Ethereum, meant to be a 1:1 representation of the native CHI coin on the Xaya blockchain.
The contract for WCHI is not upgradable and has no special "admin" functionality (i.e. no "owner" address with more rights than others, which would be like a "backdoor"). The only special role that the Xaya team has is as initial holder of the entire token supply (granted in the contract's constructor). These tokens are held in reserve, and will be distributed to users who lock CHI on the Xaya blockchain for bridging them to Ethereum.
WCHI is a minimal implementation of an ERC-20 token. In addition, we also provide a contract for HTLCs. With this, it is possible to implement atomic and trustless cross-chain swaps between WCHI tokens on Ethereum and native CHI coins on the Xaya blockchain or a future Lightning implementation.
We have deployed the contracts based on commit
52ee0049fa0798856f420d34e23bcc6be5f45ff4 as the official versions.
The smart contracts at this revision have been audited by
Solidified.
On Ethereum mainnet, the contracts are at these addresses:
We have deployed the HTLC contract natively on the Polygon (formerly Matic) mainnet, and WCHI is deployed as a standard contract for the Matic PoS bridge:
On the Mumbai testnet for Polygon, the contracts are these:
On Arbitrum One mainnet, the HTLC contract has been deployed directly, and the WCHI token has been created by the bridge (as a standard ERC-20 contract):
On xDai, we have deployed the HTLC contract natively, and WCHI through use of the OmniBridge. The addresses are:
The HTCL contract has been deployed natively on BSC, and the WCHI token though the AnySwap bridge. The addresses are:
