func (p *Provider) ContractQuery(ctx context.Context, contractAddress string, inputAbiExpr, outputAbiExpr string, args interface{}) ([]string, error)
ie, ContractQuery(context.Background(), "0xabcdef..", "balanceOf(uint256)", "uint256", []string{"1"}) TODO: add common methods in helpers util, and also use generics to convert the return for us

func (*Provider) SubscribeFilterLogs ¶ added in v1.19.0
func (p *Provider) SubscribeFilterLogs(ctx context.Context, query ethereum.FilterQuery, ch chan<- types.Log) (ethereum.Subscription, error)
SubscribeFilterLogs is stubbed below so we can adhere to the bind.ContractBackend interface. NOTE: the p.nodeWSURL is setup with a wss:// prefix, which tells the gethRPC to use a websocket connection.
The connection will be closed and unsubscribed when the context is cancelled.
func (*Provider) SubscribeNewHeads ¶ added in v1.24.0
func (p *Provider) SubscribeNewHeads(ctx context.Context, ch chan<- *types.Header) (ethereum.Subscription, error)
SubscribeNewHeads listens for new blocks via websocket client. NOTE: the p.nodeWSURL is setup with a wss:// prefix, which tells the gethRPC to use a websocket connection.
The connection will be closed and unsubscribed when the context is cancelled.

type StrictnessLevel uint8
StrictnessLevel is the level of strictness for validation when unmarshalling blocks and transactions from RPC responses from a node.
const ( StrictnessLevel_None StrictnessLevel = iota // 0: disabled, no validation on blocks or transactions (default) StrictnessLevel_Semi // 1: semi-strict transactions – validates only transaction V, R, S values StrictnessLevel_Strict // 2: strict block and transactions – validates block hash, sender address, and transaction signatures )
