To give you the lowest prices possible on your Matcha trades, we removed the 0x protocol fee from all on-chain liquidity sources (Uniswap, Kyber, Curve, etc.) To deliver this added savings, we are using a new exchange contract proxy. Users who previously approved tokens for trading will need to re-approve them to utilize the new and improved functionality. We apologize for any inconvenience that this may cause.

The Exchange Proxy address is
0xF740B67dA229f2f10bcBd38A7979992fCC71B8Eb and can be found on Etherscan here.
We do not expect any more approvals will be required in the future after the Exchange Proxy.
Matcha puts user safety first
Matcha uses the 0x protocol v3 smart contacts, which have been thoroughly tested by 0x Labs and top blockchain security companies, Trail of Bits, and ConsenSys Diligence. Learn more about the new exchange proxy here:
