What Is Walendria? A Complete Guide to walendria.org

Walendria is a trustless direct-transfer commerce protocol that lives entirely inside smart contracts on Gnosis Chain. walendria.orgis the open web app for using it: a place where a buyer and a seller who have never met can complete a paid transaction — and settle a dispute if one arises — without a bank, a marketplace, an escrow agent, or a court sitting in the middle. This guide explains exactly what the site is, how the mechanism works, and how to use it.

What is Walendria, in one paragraph?

Walendria replaces the trusted middleman that commerce between strangers has always required. In place of a reputation score, a seller locks capital: an Integrity Bond. In place of a court or a platform's support desk, a disputed transaction is judged by an open market: the Spectral Market. Payment never travels wallet-to-wallet; it settles atomically inside the contract. The whole system is immutable, has no admin keys, and runs on Gnosis Chain mainnet (chain id 100), with every value denominated in xDAI.

The problem Walendria solves

Any time two strangers transact, someone has to be trusted to make it safe: a payment processor, a marketplace, an escrow agent, a bank, a court. Each of them is two things at once — a toll booth that takes a cut, and a single point of failure that can freeze funds, reverse a payment, deny access, or simply vanish. In much of the world this is lived experience: peer-to-peer trades still route through a paid human escrow (in Indonesia, the Rekber, or “rekening bersama”) precisely because there was no trustless alternative. Walendria is that alternative. The middleman is removed, and the two questions the middleman used to answer are answered directly on-chain instead.

How it works: the two questions

Strip every trust apparatus back and only two questions remain. Walendria answers each one with a contract, not an institution.

Question one — “How do I get my money back if the seller cheats?”

The seller posts an Integrity Bond: capital locked in the contract that backs their listing. A seller is trusted because they have staked value that is at risk if they fail to deliver, not because a platform assigned them five stars. The bond self-unlocks and returns to productive use over the normal course of business; it only comes into play as the buyer's recovery if a transaction goes bad. No escrow agent ever holds the money, and no settled transfer can be reversed by a third party.

Question two — “Who decides what's true in a dispute?”

When a transaction is disputed, Walendria opens a Spectral Market— a prediction market, powered by an LMSR (logarithmic market scoring rule) automated market maker, on whether the disputed party is “guilty” or “innocent.” Anyone can take a position. As people trade, the price moves toward the outcome the market believes is true. The dispute resolves automatically once one side has held at least 93% of the price for a cumulative hour. Truth becomes an open procedure anyone can join and verify — not a verdict handed down by an authority. Evidence can be attached on-chain through the Evidence Registry so traders judge the same facts.

A transaction from start to finish

Here is the full lifecycle a buyer and seller move through on walendria.org:

1. The seller lists. On /sell, the seller posts an Integrity Bond and creates a listing against it — setting a price, a number of slots, and a completion window (a protocol-enforced minimum of 72 hours).
2. The buyer pays through the contract. Using a listing ID, the buyer pays on /listingsor the pay screen. Funds go through the contract's payment function, never directly to the seller's wallet, and any overpayment is refunded in the same transaction.
3. The seller delivers within the window. The buyer can confirm completion, which releases settlement; if the completion window lapses without a dispute, the slot can be finalized permissionlessly.
4. If something goes wrong, a dispute opens.A Spectral Market is created for that slot. Both parties — and any third party — can trade “guilty” or “innocent” and attach evidence.
5. The market resolves, permissionlessly.Once one side has held at least 93% of the price for a cumulative hour, anyone can “poke” the dispute to settle it and earn a bounty for doing so — so resolution never depends on the developer being online.
6. Winners claim. Holders of the winning side redeem their position for the payout on /claim. The buyer's recovery, when the seller is found guilty, comes from the bonded capital.

What you can do on walendria.org

The site is organized around the roles you might play. Every page reads live on-chain state (through a dedicated indexer, with a direct-RPC fallback), so what you see is the real contract state, not a cached copy.

The network, currency, and contracts

Walendria is deployed on Gnosis Chain mainnet (chain id 100), with all values in xDAI. Gnosis Chain is used because its fees are a fraction of a cent — which is what makes real, everyday-sized transactions economically viable — and because xDAI gives price stability without a custodial fiat rail. Every contract is independently verifiable on Gnosis Blockscout.

The protocol is nine contracts, each with one job:

• IntegrityBond— the bonded capital that backs a seller.
• ListingManager— listings, slots, completion windows, and the immutable 100 xDAI transaction hardcap.
• Settlement— the atomic payment path that routes funds through the contract.
• SpectralMarket— the LMSR prediction market that prices disputes.
• SettlementConditions— the 93%-for-a-cumulative-hour resolution rule and the permissionless poke.
• DisputeManager— opens and finalizes disputes and their funding.
• DeveloperPool— the protocol's fee and settlement-surplus accounting.
• EvidenceRegistry— on-chain anchoring of dispute evidence.
• SharedIB— a shared-bond variant deployed alongside the others.

The current live addresses are listed on the Prior art page and can be read from the app directly. They are not reprinted here because a fresh deploy would change them; Blockscout is always the source of truth.

Is Walendria safe? The trust model without an audit

Walendria has no paid third-party audit, and there is not going to be one — a deliberate decision. Instead of asking you to trust an auditor's sign-off, it bounds risk with properties you can check yourself:

• An immutable per-transaction hardcap of 100 xDAI caps the value exposed in any single path. It cannot be raised by anyone after deployment.
• No admin keys and no upgrade path.The contracts are immutable; there is no privileged function that can drain, pause, or rewrite them. “Upgrading” means a fresh, transparent deploy at new addresses.
• Permissionless settlement. Anyone can poke a resolvable dispute to settle it, so the system never depends on a single operator staying online.
• Open, verifiable source. The full source is MIT-licensed and every contract is verifiable on Gnosis Blockscout, so the deployed bytecode can be checked against the code.
• An independent priority record.The whitepaper's SHA-256 is notarized on-chain and archived with a permanent Zenodo DOI, so its authorship and timeline are independently checkable. See Prior art.

What does it cost?

Two things: network gas and a protocol fee. Gas on Gnosis Chain is a fraction of a cent, so the cost of interacting is negligible. A protocol fee is taken at settlement to fund the DeveloperPool; it is defined in the contracts and shown to you in the pay flow before you confirm. There is no subscription, no listing fee to browse, and no token you must hold.

Who built it

Walendria was designed, built, tested, deployed, and is operated by Panca Walendra, working solo from Bandung, Indonesia — the contracts, the indexer, the frontend, and the infrastructure. Every on-chain notarization traces to a single author address, so the project's priority chain has one provable signer. The code is open-source under the MIT license.
