Functions

func NewUptoEvmScheme() *UptoEvmScheme

Source: mechanisms/evm/upto/server/scheme.go:22

Types

type UptoEvmScheme

Source: mechanisms/evm/upto/server/scheme.go:18

UptoEvmScheme implements the SchemeNetworkServer interface for EVM upto payments (V2). Always uses Permit2 (no EIP-3009 path).

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

func EnhancePaymentRequirements( ctx context.Context, requirements types.PaymentRequirements, supportedKind types.SupportedKind, extensionKeys []string, ) (types.PaymentRequirements, error)

Source: mechanisms/evm/upto/server/scheme.go:171

EnhancePaymentRequirements adds upto payment requirements.

func GetAssetDecimals(asset string, network x402.Network) int

Source: mechanisms/evm/upto/server/scheme.go:34

GetAssetDecimals implements AssetDecimalsProvider. Returns the decimal precision for the given asset on the given network, falling back to 6 if the asset is not recognized.

func ParsePrice(price x402.Price, network x402.Network) (x402.AssetAmount, error)

Source: mechanisms/evm/upto/server/scheme.go:47

ValidatePaymentRequirements validates that requirements are valid for this scheme.
