If you would like to add a volume/fees/revenue adapter please submit the PR here.

If you would like to add a liquidations adapter, please refer to this readme document for details.

Once your adapter has been merged, it takes time to show on the UI. If more than 24 hours have passed, please let us know in Discord.
Sorry, We no longer accept fetch adapter for new projects, we prefer the tvl to computed from blockchain data, if you have trouble with creating a the adapter, please hop onto our discord, we are happy to assist you.
Please fill the form below only if the PR is for listing a new protocol else it can be ignored/replaced with reason/details about the PR
For updating listing info It is a different repo, you can find your listing in this file: https://github.com/DefiLlama/defillama-server/blob/master/defi/src/protocols/data2.ts, you can edit it there and put up a PR
Do not edit/push package-lock.json file as part of your changes, we use lockfileVersion 2, and most use v1 and using that messes up our CI

Short Description (to be shown on DefiLlama): PACT SWAP enables native BTC swaps 95% cheaper than THORChain, offers the same composability as Uniswap, supports permissionless listings, and matches the pricing users expect from retail CEX accounts — all without bridges, wrapped assets, KYCs or geo-blockers.

methodology (what is being counted as tvl, how is tvl being calculated): TVL is currently calculated soly based on tokens in the orderbook: For bid limit orders, the amount of CWEB (quote) tokens locked in the order. For ask limit orders, the amount of base tokens promised by the order as well as the additional CWEB collateral enforcing the delivery of tokens.

If I understand correctly, the liquidity in pact swap sits on each of the supported chains, and they arent bridged to coinweb chain? In which case, balances should be recorded on the chains they are deposited to, eg bitcoin, ethereum etc

Yes, they are not bridged to coinweb chain. But market maker should lock native cweb on coinweb chain to create any type of orders. Thats the reason why cweb included in tvl. Also market maker lock his tokens in destination chains, its also included in tvl.
Or may be i got you wrong?

We should count user deposits to the DEX liquidity, on the chain it is deposited on. module.exports.coinweb should be equal to the amount of assets deposited on coinweb chain

Yes, on Pact Swap user can create orders. To create any type of orders ask/bid users should lock native cweb on coinweb chain. All this locked cweb is inside orders. For ask orders users also should lock base assets and cweb as collateral for every order.
We havent got liquidity pools, we are orderbook cross-chain dex. Orders exists on coinweb chain

is it possible to read contract balances directly from the chain opposed to using your API for token amounts?

Yes, it is possible. I will update the PR

Can we not use erc20:balanceOf() and the functions in our SDK? You can return a list of addresses from your API but reading balances straight from ethers is preferred. Is this part of coinweb EVM?

odiinnn · 2025-10-14T16:41:57Z

Pact Swap workin on Coinweb chain and not Coinweb EVM Shard. Coinweb is a chain with it own stores that are not compatible with ethers. Implementation with fetching claims from https://api-cloud.coinweb.io/wallet is native way to work with Coinweb chain and its wallet service part.
Also Pact Swap smart contracts are written on Coinweb chain on typescript (language to wright smart contracts on Coinweb chain).
So in general we cannot do like you described. Coinweb is not an EVM chain and its not compatible in current stage.
Also orders is specific struct of Pact Swap Coinweb contracts. We cannot just call balanceOf. User lock theirs tokens in orders on Coinweb chain.

There is some docs with explanation of how Pact Swap works - https://docs.pactswap.io/docs/technical-architecture/coinweb-integration-deep-dive
Docs about claims in Coinweb chain - https://docs.coinweb.io/develop/reactive-smart-contracts/develop-claims-storage

Please ask questions if something not clear for you here.

I'm confused - so does pact swap have tokens in held in contracts deployed on ethereum, bsc etc or not?

odiinnn · 2025-10-14T17:04:42Z

No directly it havent got locked tokens in contracts deployed on ethereum, bsc etc. Instead of lock tokens in this contracts Pact Swap lock tokens with PACT (Penalty Adjudication for Cross-chain Transactions) mechanism. Its mean that user lock native CWEB on Coinweb chain with promise to spend his tokens on ethereum, bsc etc to unlock this locked native CWEB. There is a doc about PACT from Coinweb chain - https://docs.coinweb.io/learn/usecases/pact . And the doc how Pact Swap use this PACT - https://docs.pactswap.io/docs/technical-architecture/collateral-efficiency-and-state-machines
