func (*VM) CreateStaticHandlers 

func (vm *VM) CreateStaticHandlers() (map[string]*commonEng.HTTPHandler, error)

CreateStaticHandlers makes new http handlers that can handle API calls

func (*VM) Disconnected 

func (vm *VM) Disconnected(id ids.ShortID) error

func (*VM) FormatAddress 

func (vm *VM) FormatAddress(chainID ids.ID, addr ids.ShortID) (string, error)

FormatAddress takes in a chainID and a raw address and produces the formatted address

func (*VM) FormatLocalAddress 

func (vm *VM) FormatLocalAddress(addr ids.ShortID) (string, error)

FormatLocalAddress takes in a raw address and produces the formatted address

func (*VM) GetAtomicUTXOs 

func (vm *VM) GetAtomicUTXOs(
	chainID ids.ID,
	addrs ids.ShortSet,
	startAddr ids.ShortID,
	startUTXOID ids.ID,
	limit int,
) ([]*avax.UTXO, ids.ShortID, ids.ID, error)

GetAtomicUTXOs returns the utxos that at least one of the provided addresses is referenced in.

func (*VM) GetCurrentNonce

func (*VM) GetSpendableAVAXWithFee 

func (vm *VM) GetSpendableAVAXWithFee(
	keys []*crypto.PrivateKeySECP256K1R,
	amount uint64,
	cost uint64,
	baseFee *big.Int,
) ([]EVMInput, [][]*crypto.PrivateKeySECP256K1R, error)

GetSpendableAVAXWithFee returns a list of EVMInputs and keys (in corresponding order) to total [amount] + [fee] of [AVAX] owned by [keys]. This function accounts for the added cost of the additional inputs needed to create the transaction and makes sure to skip any keys with a balance that is insufficient to cover the additional fee. Note: we return [][]*crypto.PrivateKeySECP256K1R even though each input corresponds to a single key, so that the signers can be passed in to [tx.Sign] which supports multiple keys on a single input.

func (*VM) GetSpendableFunds 

func (vm *VM) GetSpendableFunds(
	keys []*crypto.PrivateKeySECP256K1R,
	assetID ids.ID,
	amount uint64,
) ([]EVMInput, [][]*crypto.PrivateKeySECP256K1R, error)

GetSpendableFunds returns a list of EVMInputs and keys (in corresponding order) to total [amount] of [assetID] owned by [keys]. Note: we return [][]*crypto.PrivateKeySECP256K1R even though each input corresponds to a single key, so that the signers can be passed in to [tx.Sign] which supports multiple keys on a single input.

func (*VM) HealthCheck 

func (vm *VM) HealthCheck() (interface{}, error)

Health returns nil if this chain is healthy. Also returns details, which should be one of: string, []byte, map[string]string

func (*VM) Initialize 

func (vm *VM) Initialize(
	ctx *snow.Context,
	dbManager manager.Manager,
	genesisBytes []byte,
	upgradeBytes []byte,
	configBytes []byte,
	toEngine chan<- commonEng.Message,
	fxs []*commonEng.Fx,
) error

Initialize implements the snowman.ChainVM interface
