From 4012b7ee86b46a917395823670d71c4e1ae0acd8 Mon Sep 17 00:00:00 2001 From: Owen Date: Mon, 16 Mar 2026 13:13:49 -0400 Subject: [PATCH 1/3] feat: add multisig support with partial signing for P-Chain operations Add support for multi-address ownership and threshold-based signing on P-Chain transactions, enabling multisig workflows where transactions can be built, partially signed by different key holders, and then submitted. New package pkg/multisig/: - TxFile JSON format for exchanging partially-signed transactions - ReadTxFile/WriteTxFile for file I/O - NewOutputOwners for creating multisig owners with threshold - IsFullySigned/CredentialSignatureStatus for tracking signature progress - ParseAddresses for parsing comma-separated P-Chain addresses New CLI commands (platform tx): - tx sign: add signatures to a tx file using available keys - tx commit: submit a fully-signed tx file to the network - tx inspect: display tx file details and signature status Updated commands with multisig flags: - subnet create: --owners, --threshold, --output-tx - subnet transfer-ownership: --owners, --threshold, --output-tx - validator add: --reward-addresses, --reward-threshold - validator delegate: --reward-addresses, --reward-threshold Updated pkg/pchain config structs with optional RewardOwner field that overrides single RewardAddr when set (backward compatible). --- cmd/subnet.go | 176 +++++++++++++-- cmd/tx.go | 287 +++++++++++++++++++++++++ cmd/validator.go | 110 +++++++--- pkg/multisig/multisig.go | 394 ++++++++++++++++++++++++++++++++++ pkg/multisig/multisig_test.go | 295 +++++++++++++++++++++++++ pkg/pchain/pchain.go | 96 +++++---- pkg/pchain/pchain_test.go | 12 +- 7 files changed, 1293 insertions(+), 77 deletions(-) create mode 100644 cmd/tx.go create mode 100644 pkg/multisig/multisig.go create mode 100644 pkg/multisig/multisig_test.go diff --git a/cmd/subnet.go b/cmd/subnet.go index 1ac2c6c..eb3816c 100644 --- a/cmd/subnet.go +++ b/cmd/subnet.go @@ -11,10 +11,13 @@ import ( "github.com/ava-labs/avalanchego/api/info" "github.com/ava-labs/avalanchego/ids" + "github.com/ava-labs/avalanchego/utils/constants" "github.com/ava-labs/avalanchego/utils/crypto/bls/signer/localsigner" "github.com/ava-labs/avalanchego/vms/platformvm/signer" "github.com/ava-labs/avalanchego/vms/platformvm/txs" + "github.com/ava-labs/avalanchego/vms/secp256k1fx" ethcommon "github.com/ava-labs/libevm/common" + "github.com/ava-labs/platform-cli/pkg/multisig" nodeutil "github.com/ava-labs/platform-cli/pkg/node" "github.com/ava-labs/platform-cli/pkg/pchain" "github.com/spf13/cobra" @@ -34,6 +37,11 @@ var ( subnetValBalance float64 subnetMockVal bool subnetValidatorWeights string + + // Multisig flags + subnetOwners string // comma-separated P-Chain addresses for multisig ownership + subnetThreshold uint32 // signature threshold for multisig + outputTxFile string // output unsigned tx to file instead of submitting ) var subnetCmd = &cobra.Command{ @@ -45,7 +53,13 @@ var subnetCmd = &cobra.Command{ var subnetCreateCmd = &cobra.Command{ Use: "create", Short: "Create a new subnet", - Long: `Create a new subnet on the P-Chain.`, + Long: `Create a new subnet on the P-Chain. + +For multisig ownership, use --owners and --threshold: + platform subnet create --owners addr1,addr2,addr3 --threshold 2 + +To create an unsigned tx for offline signing: + platform subnet create --owners addr1,addr2 --threshold 2 --output-tx unsigned.json`, RunE: func(cmd *cobra.Command, args []string) error { ctx, cancel := getOperationContext() defer cancel() @@ -61,11 +75,68 @@ var subnetCreateCmd = &cobra.Command{ } defer cleanup() - fmt.Println("Creating new subnet...") - fmt.Printf("Owner: %s\n", w.FormattedPChainAddress()) + // Build the owner + var owner *secp256k1fx.OutputOwners + if subnetOwners != "" { + owner, err = buildMultisigOwner(subnetOwners, subnetThreshold, netConfig.NetworkID) + if err != nil { + return err + } + } + + if owner != nil { + fmt.Println("Creating new subnet with multisig ownership...") + fmt.Printf("Threshold: %d of %d\n", owner.Threshold, len(owner.Addrs)) + } else { + fmt.Println("Creating new subnet...") + fmt.Printf("Owner: %s\n", w.FormattedPChainAddress()) + } + + if outputTxFile != "" { + // Build unsigned tx via the wallet builder, sign partially, and write to file + var ownerForTx *secp256k1fx.OutputOwners + if owner != nil { + ownerForTx = owner + } else { + ownerForTx = &secp256k1fx.OutputOwners{ + Threshold: 1, + Addrs: []ids.ShortID{w.PChainAddress()}, + } + } + + utx, err := w.PWallet().Builder().NewCreateSubnetTx(ownerForTx) + if err != nil { + return fmt.Errorf("failed to build CreateSubnetTx: %w", err) + } + + tx := &txs.Tx{Unsigned: utx} + // Partially sign with available keys + if err := w.PWallet().Signer().Sign(ctx, tx);
