Issue

The "Full Example" of using @truffle/contract to interact with contracts should include an example of listening to an event with a filter.

In the past, it used to be possible to pass a filter object on indexed event parameters when listening to an event, as seen for example [here](https://ethereum.

When passing Wasm function to the host as a callback, it's passed as an index in the table.
Wasm3 needs to provide an API to call such functions.

Testing methods like evm_mine and evm_increaseTime expect integer parameters. Unlike other methods, they reject these parameters if they are not decimal-encoded.

To reproduce

npx hardhat --version -> 2.5.0

Run npx hardhat node and make the following rpc calls:

> curl -H "Content-Type: application/json" -X POST --data \
        '{"id":1337,"jsonrpc":"2.0","method":"evm

We can safely disallow any use of solc below 0.4.25.

Just to let you know you have a problem with ABIEncoderV2 if you are trying to call a function that returns a struct.
