XRPL Integration
via TROPTIONS Protocol Fabric

The TROPTIONS Layer 0 fabric references XRPL wallets, trustlines, and stablecoin assets inside Legacy estate workflows — powering executor transfer packets, cross-chain asset snapshots, and proof anchoring through the bridge-xrpl adapter module.

Wallet References

XRPL Wallet Inventory Model

Legacy records owner-authorized XRPL wallet addresses as references — never storing private keys or seed phrases. Executor packets include wallet references so authorized executors can coordinate asset transfer through verified channels.

Classic Address

rXXXX...XXXX

r-prefix, base58

X-Address

X7XXXX...XXXX

Encodes destination tag

Destination Tag

optional uint32

Required by some exchanges

Network

Mainnet / Testnet

Label clearly in inventory

Security note: Legacy never stores XRPL private keys, seed phrases, or secret keys. Only the public r-address (and optionally an X-address or destination tag) is recorded in the vault inventory. All private key custody remains with the owner or their hardware wallet.

Bridge Module Status

bridge-xrpl Crate

Troptions-L1 includes a bridge-xrpl Rust crate that models XRPL trustline and transaction routing as a simulation-only cross-rail adapter. Live bridge execution requires operator keys, a live XRPL RPC endpoint, and Control Hub approval.

SIMULATION

bridge-xrpl crate

Rust scaffold — simulation-only until live operator enabled

ADAPTER

Trustline management

Model-ready — no live key execution

ADAPTER

Executor transfer routing

Packet generation ready — live bridge requires operator keys

SCAFFOLD

Proof anchoring

TROPTIONS Layer 0 anchor event model ready

BLOCKED

Live bridge execution

Requires live XRPL operator keys, RPC, and Control Hub approval

x402 Integration

XRPL-powered x402 Services

PRODUCTION_REQUIRES_GATEWAY

XRPL Proof Packet

Signed XRPL wallet reference and trustline proof packet for executor proceedings — metered via TROPTIONS x402.

Cross-chain Asset Snapshot

Multi-chain wallet snapshot including XRPL addresses, trustline balances, and RLUSD references.

Current Status — Adapter / Simulation

• bridge-xrpl crate: Rust simulation adapter — no live XRPL execution enabled
• Trustline management: model-ready, no live key execution
• Stablecoin assets (USDC, USDT, EURC, RLUSD): watched/referenced only — not issued by Legacy
• USDF/FTHX: planned rail — issuance simulation-gated, legal review required
• Live bridge requires: XRPL operator account, RPC credentials, Control Hub approval, legal sign-off
