ArbiSecure: Trustless service escrows on Arbitrum Stylus. Secure, low-gas payment links for the global gig economy that ensure instant settlement and eliminate platform fees.
ArbiSecure is the first self-enforcing escrow protocol built on Arbitrum Stylus. It utilizes programmable milestone releases to prevent disputes before they happen, backed by a decentralized network of staked arbiters for edge cases.
In the global freelance economy, high-value work faces a "Trust Gap." Clients fear non-delivery, and freelancers fear non-payment. Traditional escrow is slow, expensive, and relies on manual client approval, which often leads to delays and "ghosting."
ArbiSecure solves this by automating trust.
Instead of waiting for a client to manually click "Approve," ArbiSecure deals use pre-approved release conditions. When verifiable on-chain or off-chain events occur (e.g., a GitHub PR merge, an API health check, or a specific date), funds are released automatically.
Preventative Escrow: 90% of payments release automatically based on code/data, not human opinion.
Arbitrum Stylus (Rust): Achieving 80%+ gas savings compared to Solidity, making micro-milestones economically viable.
Staked Arbiter Network: A marketplace of reputation-backed arbiters for subjective disputes.
Gasless Onboarding: First deal is always free via Biconomy Paymaster.
The heart of ArbiSecure is the ability to attach logic to money. At deal creation, both parties agree to specific conditions.
Time-based: Auto-release after X hours/days.
Oracle-verified: Uses Chainlink Functions to verify external data (GitHub commits, API status).
Hybrid: "Release when PR #42 is merged OR 48 hours have passed."
For subjective work (e.g., "Is this logo design good?"), human arbitration is still needed.
Staking: Arbiters must stake 500 USDC to participate.
Slashing: Arbiters who collude or fail to respond lose their stake.
Reputation: On-chain tracking of dispute resolution speed and fairness.
Disputes are not just chat logs. ArbiSecure uses a structured evidence flow:
Users upload proof (screenshots, logs) to IPFS.
Content-addressed hashes are stored on-chain.
Arbiters review immutable evidence to make rulings.
ArbiSecure leverages the performance of Arbitrum Stylus to handle complex logic efficiently.
Component | Technology | Purpose |
Smart Contracts | Rust (Stylus SDK) | High-performance state management & condition checking. |
Network | Arbitrum Sepolia | Low-cost L2 execution. |
Oracles | Chainlink Functions | Verifying off-chain events (GitHub/API). |
Frontend | Next.js + RainbowKit | User interface & wallet connection. |
Security | OpenZeppelin Stylus SDK | ReentrancyGuard, AccessControl. |
UX | Biconomy Paymaster | Gasless transactions for new users. |
How we handle conditional releases efficiently in Rust:
enum ConditionType {
TimeElapsed, // Block timestamp check
OracleConfirmation, // External data feed (Chainlink)
ManualApproval, // Client signature
HybridAll, // All conditions met
}
#[external]fn check_and_release_milestone(deal_id: U256, milestone_index: u8) {
let mut milestone = self.get_milestone(deal_id, milestone_index);
// Check all pre-approved conditions
let all_met = milestone.conditions.iter().all(|c| c.met);
if all_met && !milestone.released {
self.release_milestone_funds(deal_id, milestone_index);
}
}
