Composable inference

LiquidPad connects to the Liquid Protocol wstDIEM Inference Vault — the on-chain layer that turns DIEM staking into Venice AI inference capacity. Here's where we stand and where we're headed.

On-chain status (live)

AgentTGERegistry

Not registered

Registration pending — requires Liquid team to call register().

X402Adapter

Inactive (v6)

Adapter contract exists but is unregistered on the v6 vault. Opportunity to reactivate.

Integration paths

AgentTGERegistry

ready

Register LiquidPad as an agent in the vault's on-chain registry. Enables tier-based inference allocation + dormancy tracking. We already query it live.

Pending: owner (Liquid team) registers our operator wallet.

X402Adapter → InferenceVault

proposed

Route a portion of LiquidPad's x402 USDC settlements through the X402Adapter. Makes LiquidPad a direct inference-revenue source for the vault. Adapter contract exists but is unregistered on v6.

Proposed to Liquid team. Needs adapter redeployment + vault registration.

InferenceProduct consumer

future

Buy on-chain inference capacity from the vault's InferenceProduct instead of using Venice keys directly. Fully composable — LiquidPad becomes an on-chain inference buyer, not just an API consumer.

Future: after AgentTGERegistry + X402Adapter are live.

How x402 → Vault works

agent calls /api/x402/inference
  → pays $0.01 USDC (settled via Coinbase CDP facilitator)
  → LiquidPad receives USDC
  → portion routes to X402Adapter.recordX402Settlement(amount)
  → adapter accumulates USDC
  → keeper calls routeYield() → swap USDC → DIEM → vault.creditDIEM()
  → wstDIEM holders earn yield from LiquidPad's inference revenue

This is the path we're proposing. It makes LiquidPad a direct inference-revenue source for the wstDIEM vault.

Vault contracts (Base mainnet, v6)

Contract	Role	Address
InferenceVault (wstDIEM v6)	ERC-4626 vault. Deposit DIEM → mint wstDIEM. Yield from inference revenue.	0xe49F…67ba
AgentTGERegistry	Tracks agent lifecycle: Bronze/Silver/Gold tiers, 30-day dormancy.	0xb138…98Ef
InferenceProduct	On-chain USDC settlement for Venice inference capacity. Buyers purchase time-bounded allocations.	0xE43c…a5F3
FeeRouter	Aggregates protocol fee income (WETH/USDC/VVV/wstDIEM). Routes per a configurable FeeMode.	0xa13a…4ED3
X402Adapter	Venue adapter for x402 settlement USDC. Receives inference payments and routes yield to vault.	(not active on v6 — opportunity)
