Coming soon. Solver Credit is in design as the first product of the Shared Collateral Network. Mechanics below describe the planned shape; parameters publish at launch.

​
The Inventory Tax

A cross-chain fill needs destination capital for seconds to minutes - until the fill proof releases the user’s escrowed source funds. Today that capital is pre-funded inventory: your working capital, warehoused on every chain and asset you serve, sized for the peak, earning nothing between fills, hedged and rebalanced by hand. It carries a cost of carry, a basis risk and an ops desk - and every dollar parked in it is a corridor you cannot quote and a spread you cannot tighten.

​
The Vault Fills, You Price

Solver Credit is a solver credit vault: pooled, one-sided liquidity that fronts your fills just in time on any supported chain, hedges the two-sided trade underneath, and rebalances itself once settlement lands. What automated market makers did to market making, this does to the inventory desk: it becomes a shared, automated layer, and you keep the part that is yours - pricing, and the margin on it.

​
What Changes for You

  • Zero collateral. No bond, no margin, no pre-funding. The fill itself is the security: the vault fills, so the vault holds the claim on the escrow.
  • Asset-light unit economics. Per fill: spread captured, minus one small fee. No cost of carry, no hedging cost, no bridge cost, no idle float. Inventory leaves your balance sheet, and return on capital goes up with it.
  • One line, every supported chain. One number across chains, sized on your settlement track record rather than on what you could afford to park. A new chain is a limit, not a warehouse - quote it on day one.
  • Any venue you already fill. A credit facility, not a venue feature: draw it on TetraFi flow or on any intent venue you serve. One credit relationship, every book you run.
  • Spread locked at award. The vault sources the fill asset and carries the basis between fill and settlement. No delta, no hedge desk.
  • No bridge desk. Cross-chain repayments leave the vault short on one chain and long on another - its problem, not yours, and none of it is your transaction to send.

​
How It Works

  1. The vault fills. On award, the credit engine signs the exact fill action; the vault pays the settlement contract and executes it in one transaction. The money never touches your wallet, and a reverted fill is no draw.
  2. The vault hedges. The fill asset is sourced against the pool’s deposits - borrowed on a money market or swapped, under on-chain health and exposure caps - so the position is delta-neutral from fill to settlement.
  3. The escrow repays. The user’s source funds were locked with the vault as claimant. When the fill proof lands, the escrow releases to the vault: debt cleared, hedge unwound, fee accrued to depositors.
  4. The vault rebalances. Counterflow and netting first, an allow-listed bridge last, and only for an aged residual. No draw or settlement ever waits on it.

​
Why Zero Collateral Works

  • A claim, not a promise. The vault performed the fill, so it is the claimant on the escrow that fill unlocks - the moment you fill, it can claim. Every draw is a per-solver ledger entry with a deadline.
  • You never custody anything. The pool executes; you instruct. User funds and pool funds never sit in your wallet, so there is nothing to misdirect and nothing to safeguard.
  • Capped on-chain. Every hedge sits under a health factor; every solver under per-chain sub-limits and a per-draw cap; irregular repayment trips a circuit breaker.

​
Terms

  • Fee - a small, fixed charge per use; it scales with the number of trades you put through, nothing else.
  • Line - sized on settlement track record and chain, and re-cut upward as your volume grows.
  • Shared liquidity is just-in-time and may decline - a declined draw never touches your own inventory path. Dedicated facilities add a committed cap and a per-draw limit.
  • Compliant by construction. Every counterparty in the pool is KYB’d and every draw is policy-gated, on the rails that gate everything else on TetraFi - credit you can take onto a regulated balance sheet.
Solver Credit is the first dollar through the network: TetraFi’s own solver flow proves the mechanism before it opens to every solver, on every venue.
