The encyclopedia of onchain experiments

An anonymously-built, fully onchain prediction market that launched inside Phantom wallet on Solana using Chainlink oracles, then migrated to Robinhood Chain a week later.

Solana launchpad that let anyone create a token by replying to an X account, branded as 'Internet Capital Markets' for startups — it minted thousands of coins a day at its peak before collapsing 99.8% amid a botched token migration, a class action, and the founder's arrest.

Solana memecoin launchpad that hardcodes a perpetual 1% trading-volume royalty to creators (and socially-verified 'fee split' recipients) into every token at launch.

Coinbase-incubated open standard that revives the dormant HTTP 402 'Payment Required' status code so APIs, apps, and AI agents can pay for web resources with stablecoins directly inside the HTTP request/response cycle.

Berachain's Layer-1 consensus-adjacent incentive system that paid block emissions in a soulbound token (BGT) directed by validators to DeFi liquidity vaults — bootstrapping $3B+ TVL before an 88% collapse forced its replacement with a single-token model in 2026.

A 'synthetic dollar' that holds its $1 value not with bank reserves but with a delta-neutral basis trade — long staked crypto collateral, short an equal notional of perpetual futures — passing funding + staking yield to sUSDe stakers.

An oracle-free perpetual-options protocol that reinterprets Uniswap v3/v4 concentrated-liquidity positions as short options, letting anyone mint, trade, and market-make never-expiring puts and calls on any token.

Karma3 Labs' decentralized reputation-compute protocol that ran EigenTrust over onchain and social graphs to power verifiable rankings, feeds, and sybil-resistant airdrops — technically validated but shut down in 2026 for lack of a business model.

A fully shielded proof-of-stake L1 and private DEX for the Cosmos/IBC ecosystem that made privacy the default for transfers, staking, swaps, and governance — technically landmark, commercially marginal.

A 'Dynamic Distribution AMM' whose liquidity bins automatically shift with price, letting LPs run directional and auto-recentering strategies — a technically influential DEX design whose volume-to-TVL efficiency never converted into durable liquidity or market share.

A single-contract DEX (formerly CrocSwap) that fused full-range, concentrated, and knockout limit-order liquidity into one AMM — technically ahead of Uniswap v4 but commercially eclipsed after points-driven TVL evaporated.

Biometric proof-of-personhood network that scans irises with a custom 'Orb' to issue privacy-preserving zero-knowledge World IDs, paired with the WLD token and its own L2, World Chain.

A zkTLS oracle protocol that lets users prove facts from any HTTPS website (identity, finances, activity) on-chain without exposing the underlying data or requiring the website's cooperation.

TRON's dollar stablecoin that launched in May 2022 as a Terra-style algorithmic coin backed by the TRON DAO Reserve, depegged repeatedly, and was relaunched in January 2025 as a MakerDAO-style overcollateralized CDP system with a Peg Stability Module.

Solana stablecoin backed 1:1 by delta-neutral perpetual-futures positions that held its peg through the Mango Markets exploit but never found product-market fit and voted itself out of existence in 2024.

Trader Joe's bin-based concentrated-liquidity AMM that made LP positions fungible and priced fees dynamically with an on-chain volatility accumulator.

A BNB Chain-native 'stableswap 2.0' AMM that replaced Curve-style paired pools with single-sided deposits priced by an asset-liability coverage ratio, hit ~$215M TVL within months, spawned its own veToken 'WOM Wars' — then bled to near-irrelevance as stableswap volume consolidated elsewhere.

A Frax-style partially collateralized stablecoin (IRON) on BSC and Polygon whose share token TITAN hyperinflated to near-zero in June 2021 in what the team called crypto's first large-scale bank run.

A credit-based (collateral-free) algorithmic stablecoin on Ethereum that suffered a $182M flash-loan governance takeover in April 2022, recapitalized via a debt sale, and relaunched with governance moved off-chain.

Decentralized euro (agEUR/EURA) and dollar (USDA) stablecoin protocol that pioneered hedging-agent and Transmuter price-stability designs, survived collateral loss in the Euler exploit, but voted to wind down in 2026 as the team pivoted to Merkl.

A multichain DEX that replaced AMM bonding curves with an RFQ model in which professional market makers cryptographically sign off-chain quotes for zero-slippage, MEV-protected on-chain settlement.
