For practical implementation insights, review our docs as well as the [clr.fund](https://github.com/clrfund/monorepo/) and [QF](https://github.com/privacy-scaling-explorations/qf) repositories as reference implementations. Both are quadratic funding implementations, a mechanism which otherwise is highly susceptible to collusion and bribery. Most notably, clr.fund is already working on integrating MACI v1.2.0, after having used v0.x until now. You can follow their development effort under this [GitHub branch](https://github.com/clrfund/monorepo/tree/feat/maci-v1).

When passed to the circuit, the code would perform the ECDH operation by performing a scalar multiplication between the public and the coordinator private key. This happens inside the [`MessageToCommand`](https://github.com/privacy-scaling-explorations/maci/blob/v1.2.0/circuits/circom/messageToCommand.circom#L41) template, which calls the [`ECDH` template](https://github.com/privacy-scaling-explorations/zk-kit/blob/main/packages/circuits/circom/ecdh.circom). Here, there is a call to [`escalarMulAny`](https://github.com/privacy-scaling-explorations/zk-kit/blob/main/packages/circuits/circom/ecdh.circom#L26) which in turns calls [`SegmentMulAny`](https://github.com/iden3/circomlib/blob/master/circuits/escalarmulany.circom#L154), where we encounter the final call to [`Edwards2Montgomery`](https://github.com/iden3/circomlib/blob/master/circuits/escalarmulany.circom#L78) where the error pops up.
