logos-evm-wallet-backend-module
The coordinator for the Logos multi-chain EVM wallet (Rust, rust-first
cdylib). It depends on
eth_rpc_module,
keystore_module, and
token_list_module,
and it also folds in the tx-builder (offline alloy ABI/tx construction).
It owns the central proxy + chain config (and pushes each chain's {endpoint, proxy, proxyRequired} down into eth_rpc), fetches multi-chain balances with
Multicall3 (one eth_call per chain, falling back to per-call), orchestrates
sends (build → sign → broadcast → record), and stores this wallet's own
transaction history (the only history available without a proprietary indexer).
Contract (WalletBackendModule)
Config: set_proxy_config/get_proxy_config, set_chains/get_chains,
test_endpoint. Accounts: create_account, import_mnemonic, list_accounts,
unlock/lock. Watched tokens: set_watched_tokens/get_watched_tokens.
Tokens: get_tokens, add_custom_token. Balances: refresh_balances,
get_balances. Send: estimate_fee, send_native, send_erc20. History:
get_history, refresh_tx_status. Events: balances_updated,
tx_status_changed, proxy_error.
Build & test
cd rust-lib && cargo test --no-default-features # tx-builder (incl. Multicall3), config, history
nix build .#install # -> result/modules/wallet_backend_module/
Building the full module pulls the three dependency modules' published .lidl
contracts to generate the typed modules().<dep> clients. In the Logos workspace
they resolve via flake follows/--override-input to local checkouts.
