test: replace ganache with anvil (#1286)
* ci: install anvil

* test: use anvil instead of ganache

* ci: fix anvil ver

* ci: re-enable example tests

* test: remove unnecessary assertions

* test: enable anvil launch test

* docs: typo

* test: fix anvil chain id

* ci: install ganache

Ganache is needed for the Ganache tests

* chore: remove legacy feature from some examples

* ci: correctly build examples

* test: use correct account balance for anvil

* chore: remove sub_id == 1 check

this was only possible in ganache because it gives serial
sub ids, but in every other reasonable client the ids are generated
randomly, so we cannot test for its value

* test: ensure txs are different

There is a bug in Ganache's mempool which accepts duplicate transactions (here with the same nonce), whereas here we pre-set all the nonces so that they end up having a different transaction hash.

* test: ignore ganache tests

* fix: terzor api changes

* ci(examples): install Anvil, remove geth/ganache

* test(provider): Anvil instead of Geth

some tests start to fail now

* fix: revert usage of Anvil in ipc tests

Anvil does not support IPC yet

* fix: update examples script

* ci: use anvil for wasm example

* replace last ganache usage

Ensure a consistent chain ID between a signer and provider in SignerMiddleware (#1095)
* feat(middleware): fetch chainid from middleware

Require SignerMiddleware to fetch the inner middleware's to set for the
signer. SignerMiddleware now requires an instantiated middleware with
an accessible get_chainid method.

* ci: update ganache

newer ganache version is needed to specify the ganache provider chain id
in tests

* set SignerMiddleware constructor return to result

* create new method for pulling chainid

* add consistent chainid CHANGELOG entry

* remove awaits

* switch test_derive_eip712 to use consistent signer

 * remove gas estimation equality assert in deploy_and_call_contract -
   updated version of ganache no longer returns the same value for gas
   estimation and gas_used

* revert with_signer to non-async non-result

* cargo fmt

* expand SignerMiddleware::new comment

* remove doc indent

Expose New `call_raw` API that permits MultiCalls without Detokenization (#915)
* Add `call_raw` method that forgoes detokenization for MultiCall. Have `call` wrap around `call_raw` permitting user to handle detokenization themselves if they wish

feat(ethers-contract): add `send_with_receipt` to `Deployer` (#865)
* feat(ethers-contract): add `send_with_receipt` to `Deployer`

The `Deployer` is used to deploy contracts and its `send`
function returns an attached instance of a `Contract`.
There is no way to know the transaction hash of the
deployment transaction, so this commit adds another
method `send_with_receipt` that returns an attached
`Contract` as well as a `TransactionReceipt`.

* changelog: update

* tests: call `send_with_receipt` in tests

fix: eip712 signing with ledger hw (#518)
* fix: eip712 signing with ledger hw

This commit fixes the way a EIP712 derived struct is sent to the
Ledger HW to obtain the signature.

It also checks if the Ledger ETH app is at least 1.6.0 since this
is a requirement.

derive-eip712: initial implementation of eip712 derive macro (#481)
* derive-eip712: initial implementation of eip712 derive macro

This commit provides an initial implementation for a derive macro
to encode typed data according to EIP-712, https://eips.ethereum.org/EIPS/eip-712

Additionally, this commit introduces a new signer trait method:

    async fn sign_typed_data<T: Eip712 + Send + Sync>(
        &self,
        payload: &T,
    ) -> Result<Signature, Self::Error>;

And implements the new method for each of the signers (wallet, ledger,
aws).

Additionally, these changes include using `WalletError` for the Wallet
signer error type

At the moment, derive does not recurse the primary type to find nested
Eip712 structs. This is something that is noted in the source and
currently responds with an error regarding custom types.

A subsequent PR should be opened once this issue becomes needed. For the
moment, the current implementation should satisfy non-nested, basic struct types.

* rename to ethers-derive-eip712; move to ethers-core

* refactor of derive-eip712 macro; use ParamType and EthAbiToken

* macro updates; add byte array checker for paramtype; use literal constant for domain type hash

* replace std::convert::Infallible with WalletError as Wallet signer error type

* update workspace members and dev dependencies for examples folder

* add example for eip712 and test against contract

* remove extraneous backward slash in '\x19\x01' prefix; example tests pass

* update unreleased change log

* remove print statements

* use parse_macro_input macro; remove dead code; handle nest struct not implemented error

* move eip712 example to solidity-contract tests folder; update cargo workspace dependencies

* allow optional EIP712Domain parameter when encoding eip712 struct and signing typed data

* add documentation for eip712 feature

* Update ethers-signers/src/ledger/mod.rs

Co-authored-by: Sebastian Martinez <me@sebastinez.dev>

* add error enum for Eip712Error; use sign_payload for ledger signer

* add EIP712WithDomain type for providing a wrapper around custom setting of the domain

* make LedgerWallet sign_payload public

* use optional feature gated dependencies for eip712; add default method for encode_eip712

* add default domain_separator method, pre-compute separator hash

* move derive-eip712 deps to dev deps

feat(ethers-contract): typed txs (part 4) (#362)

Replace contract client references with Arc (#35)
* feat(provider): allow specifying a default polling interval param

This parameter is going to be used for all subsequent client calls by default. It can still be overriden with the internal
`interval` calls

* feat(contract): replace reference to Client with Arc

* feat(abigen): adjusts codegen to use Arcs

* fix(ethers): adjust examples to new apis

* fix(provider): return TxHash instead of PendingTransaction on tx submission

Returning a PendingTransaction allowed us to have nice ethers.js-like syntax where you submit
a transaction and then can immediately await it. Unfortunately, now that we use Arcs and not lifetimes
this meant that we would need to bind the function call in a variable, and then await on it, which is pretty
bad UX.

To fix this, we revert back to returning a TxHash and introduce a convenience method on the provider and the
contract which takes a tx_hash and returns a PendingTransaction object. The syntax ends up being slightly
more verbose (although more explicit), but the issue is fixed.

feat(signers): make Signer on Client optional (#34)
This allows using Contract either in read-only mode (e.g. for fetching data/events)
or for using the accounts on the node as senders

Add streamed logs to the provider (#9)
* feat(provider): implement Streamed logs

This utilizes eth_getFilterChanges. The stream struct must be instantiated with a factory that yields logs/hashes.
Consumers are expected to use the `FilterStream` trait in order to simplify their type definitions

* feat(provider): expose streaming methods

* test(provider): add new blocks/pending txs test

* feat(contract): allow events to be streamed

* test(contract): add integration test for streaming event logs

* perf(contract-factory): take abi and bytecode by value instead of reference

The abi, bytecode and the factory's deploy method now consume the structs instead of being passed by reference. While this means that
consumers might need to clone before using them, this gives us some more flexiblity around factories inside helper functions

* refactor(contract): use test helpers to reduce code dup

* chore: make clippy happy
