Costory is a decentralized, non-custodial liquidity and risk-cover protocol built on the Flare Network. It is an on-chain insurance layer for DeFi — large-cap assets like XRP (via wrapped FXRP) are staked as collateral to underwrite smart-contract, oracle, and bridge risks.

The problem

DeFi got big.
Cover didn't

Costory is the risk-cover layer between DeFi capital and the contracts it trusts. Staked collateral, transparent pricing, and on-chain claims — so a protocol failure doesn’t mean total loss.

Before · unprotected

Exploits meant total loss.

Billions locked across smart contracts, oracles, and bridges — with no on-chain safety net when they break.

One exploit, and the capital was gone for good.

Now · with Costory

Risk is covered.

Stake FXRP, buy cover, get paid on verified failure. Fully on-chain, non-custodial.

Losses are underwritten. Anyone can insure a position.

The gap · real protection

What happens when a bridge fails?

Most DeFi has no insurance. When a contract, oracle feed, or bridge is exploited, depositors absorb the entire loss.

Costory turns that unhedged risk into a priced, tradable, on-chain cover.

What it is

The missing risk-cover layer
for decentralized finance

01

Turn idle FXRP into productive underwriting collateral

Costory lets holders stake wrapped XRP and other large-cap assets into risk pools that underwrite smart-contract, oracle, and bridge failures — earning premiums for the risk they take on.

02

Get covered,
not just exposed

Anyone can lock capital in a DeFi protocol in seconds. Protecting it is the hard part: exploits, oracle manipulation, bridge hacks. Costory prices and covers that risk.

03

Costory doesn't just insure,
it pays out

Buy cover, stake collateral, file a claim, and receive a payout on a verified failure — all trustlessly, enforced by smart contracts on Flare.

04

The same cover for the protocols your capital touches

DEXes, lending markets, and bridges plug into the same risk pools. They draw on the same staked collateral and transparent pricing, through one on-chain protocol.

Coverage

Risk cover reaches every corner of DeFi

Legacy insurance is centralized and opaque. Costory pushes non-custodial cover into the protocols and wallets you already use.

Smart-contract cover

Protection against exploits, reentrancy, and logic bugs in the contracts you deposit into.

MCP

XRP, FXRP, and other large-cap Flare-bridged assets, staked as underwriting collateral.

Oracle cover

Protection against manipulated or stale price feeds that trigger bad liquidations and depeg events.

Bridge cover

Protection for assets in transit across bridges — the single biggest source of DeFi losses to date.

App

Stake, buy cover, track pools, and manage claims from a clean non-custodial dashboard.

Unprotected vs covered

Unhedged DeFi vs
the risk-cover layer

Depositing into a raw DeFi protocol gives you yield and full downside. Costory gives you priced, on-chain protection.

In practice

What using Costory looks like

Launch app

Launch app

When you stake

"Stake 50,000 FXRP into the lending-market cover pool."

Costory locks your collateral, mints a cover position, and starts earning premiums from protocols buying protection against that pool.

When you buy cover

"Insure $250,000 of deposits in this DEX against a smart-contract exploit for 90 days."

Costory quotes an on-chain premium, issues the cover, and — if the exploit is verified — pays your claim from the staked pool automatically.

How it works

From wallet to cover in minutes

1/ Connect

Connect a Flare-compatible wallet and bridge in XRP as FXRP, or bring other large-cap assets.

2/ Stake or cover

Stake collateral into a risk pool to earn premiums, or buy cover to protect a DeFi position.

3/ Stay protected

Your cover runs autonomously on-chain. Premiums accrue to stakers; policies stay live for their full term.

4/ Claim

If a covered failure is verified on-chain, file a claim and receive your payout directly from the pool.

Pricing

Pay a premium for cover,
not your whole position.
