Choose a market
Compare price, range, reference fees, and risk.
Markets move.
Your capital can work with them.
ArcSpring brings market-liquidity references, vault previews, isolated lending, and Arc infrastructure into one experience. This guide explains the essentials without hiding the execution boundary.
01 · VAULTS
A simple way to understand an onchain liquidity position.
Choose a market, enter a USDC amount, inspect the expected allocation and refund, then review the exact asset and network. ArcSpring reproduces this flow without pretending a transaction can execute.
Enter USDC
See the illustrative invested amount and unused refund.
Review the position
Verify asset, network, and contract status in one place.
Withdraw when ready
Choose proportional tokens or a protected USDC conversion path.
02 · SAFEGUARDS
Guardrails are part of the product.
ArcSpring separates market observations from Arc execution. If a required contract, price, or quote is unavailable, the sensitive action waits.
Bounded execution
Price movement, trade size, slippage, and maximum authority must all have public limits.
Separated controls
Operations, emergency pause, and treasury authority should use distinct roles.
Visible source labels
Reference-market figures never masquerade as Arc liquidity or wallet balances.
Flexible exits
A production vault should preserve proportional-token exits when a one-click swap is unavailable.
03 · ARC INFRASTRUCTURE
One dollar-native rail, several ways to move.
Arc combines stablecoin gas with Circle’s application and crosschain infrastructure. Every named primitive carries its icon and its precise role.
Stablecoin gas
The asset users move is also the asset that pays Arc network fees.
Application orchestration
Wallet, send, swap, and bridge primitives share one Arc-native application layer.
Crosschain transfer
Burn-and-mint USDC movement avoids wrapped representations.
Unified balance
A single USDC balance can support movement across connected chains.
04 · THE EXECUTION LOOP
Evidence feeds back into every action.
The same flow appears across vaults, lending, and trade: observe the market, construct a bounded quote, review every consequence, and record the final receipt.
Observe live state→Build bounded quote→Review exact action→Link the receipt
05 · ORACLE SAFETY
Fresh reference prices come before speed.
A pool price alone is not enough for a price-dependent deposit, loan, liquidation, or swap. An Arc deployment must compare a current independent reference with the executable venue immediately before the wallet opens.
ArcSpring safety rule
No fresh price, no price-dependent action. Existing proportional exit paths should remain visible.
06 · SMART CONTRACTS
Verify, don’t trust.
These are official Arc Testnet infrastructure contracts. ArcSpring vault and lending contracts are not deployed.

Interfaces first. Contracts only after the evidence.
The roadmap moves from complete product interaction to verified testnet contracts and then a capped, reviewed launch.
Reference-complete interface
Vault, deposit, withdrawal, lending, trade, portfolio, help, and status flows.
Verified Arc contracts
Publish source, roles, caps, oracles, exit paths, and explorer evidence.
Independent review
Audit every capital path and validate monitoring, pause, and recovery procedures.
Observed production
Start small and raise limits only when onchain behavior supports it.
