Overview ¶

Package evm reads an Ethereum-compatible wallet (Ledger, MetaMask…) from its public address: native coin and ERC-20 history and balances, on one or more networks. Nothing is signed and no secret is needed.

Data comes from each network's Blockscout instance through its Etherscan-compatible API (module=account: txlist, txlistinternal, tokentx, balance, tokenbalance), or from Etherscan's v2 API (one host, chainid parameter) when an Etherscan key is given.

Limits of this first version:

a swap on a DEX shows as its two legs (a Withdrawal of what was sent and a Deposit of what was received), not as a Trade;
spam tokens are skipped by heuristics (see spam), and well-known symbols (USDC, USDT, DAI, WETH, WBTC) only count from their canonical contract, so a counterfeit "USDT" airdrop is ignored;
the L1 data fee of rollups is added when the API returns it (l1Fee, L1FeesPaid); Blockscout's txlist does not, so ETH on L2s can show a tiny reconciliation gap.

Constants ¶

View Source

const All = "all"

All is the "chains" value that reads every supported network.

Variables ¶

Functions ¶

func Networks ¶

func Networks() []string

Networks lists the supported networks by name.

func New ¶

func New(cfg source.Config) (source.Source, error)

New builds the connector from its settings.

Types ¶

type Chain ¶

type Chain struct {
	Name    string // as typed in the settings
	ID      int    // EIP-155 chain id (Etherscan v2, Blockscout PRO)
	Native  string // native coin symbol
	Decimal int32
	// Free: an Etherscan-compatible explorer that answers without a key
	// ("" when none does any more).
	Free string
	// Pro: indexed by Blockscout's PRO API, free with a key.
	Pro bool
}

Chain is a supported network.

type Source ¶

type Source struct {
	// contains filtered or unexported fields
}

Source is a configured wallet.

func (*Source) State ¶

func (s *Source) State() []byte

func (*Source) Test ¶
