![](data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" width="400" height="400"><rect fill-opacity="0"/></svg>)
by FerrunsOP-Sign is a trustless document notarization protocol built on OPNet, Bitcoin's Layer 1 smart contract platform. It lets anyone prove that a specific document existed at a specific Bitcoin block height, attested by a specific signer — with no intermediaries, no servers, and no trusted third parties.
Orange Dollar
by Muad'DibA stable unit of value is essential for any economy to work efficiently. Orange Dollar provides stability while allowing investors to earn on the volatility of the underlying backing.
OpDrop
by DannysPayPigToken airdrop tool for OPNet — Bitcoin L1 smart contracts. Drop tokens to hundreds of addresses in one click, or set up a merkle claim pool and let recipients come to you.
BlockTip
by FrenchchocolatineBlockTip — The first tip bot on Bitcoin L1. Send any OP_20 token to anyone in one click, or stream it block-by-block like a slow drip of liquid sats. Hold $BLOCK for cheaper fees. Flex on the leaderboard. Built on OP_NET, where tipping finally feels native to Bitcoin. Stop tipping in fiat. This is Bitcoin. 💸
SatStash
by FerrunsSatStash is a Bitcoin L1 DeFi application built on OPNet that lets users swap tokens and automatically route "dust" into a time-locked savings vault — all in a single transaction.

Faucet Decentralizator
by FrenchchocolatineExhausted to search the faucet you need ? Faucet centralizator is the answer. 1 rule to beat'em'all. You can create a faucet, you can claim. EZPZ, I like the old fashion way
OPfun
by EllyOPfun is the pump.fun of Bitcoin L1 — a no-code token launcher built on OP_NET. Users can deploy custom OP_20 tokens to Bitcoin L1 in 60 seconds by simply filling out a form with their token name, ticker, and supply. No coding required. Built with React, Tailwind CSS, and the OP_NET framework, OPfun brings the fastest memecoin/token launch experience from Solana to Bitcoin's base layer.
Eternal Sentinel
by FerrunsEternal Sentinel is a decentralized, progressive Dead Man's Switch vault built directly on Bitcoin L1 via OPNet. It acts as a trustless, automated inheritance protocol that protects an owner's BTC by requiring them to periodically "check in" to prove they are alive. If the owner's heartbeat lapses, the smart contract automatically triggers a two-tier release of the funds to a designated beneficiary: Tier 1: 10% of the vault is unlocked after roughly 6 months (26,280 blocks) of inactivity. Tier 2: The remaining 90% is released after 12 months (52,560 blocks), permanently finalizing the contract.
MotocatRoulette
by PirataVTFun Defi Gaming, gamble for moto,
Jeet Tracker
by TryptoTelegram bot that tracks and notifies of wallet transactions.
OP_Token Forge
by AndarkOne-click OP_20 token factory on native Bitcoin L1. Describe name/symbol/supply → instant deploy with caller as owner. Unlocks true native memecoins & DeFi primitives without bridges or wrapped assets.
Scramble
by HappyPathScramble Protocol is a DeFi yield game built on Bitcoin Layer 1 through OPNet smart contracts. No bridges, no wrapped tokens. Users deposit MOTO tokens into The Pan (a vault), where they are farmed for yield via MotoChef and compounded automatically. Early withdrawals are penalised with The Yoke Tax — a block-height-based fee that gets redistributed to loyal holders. The longer you stay, the more you earn through Cook Levels (loyalty multipliers) and The Sizzle (a reward drip that streams fees and yield over ~7 days). The protocol has its own token, $EGG, which serves multiple roles: - Free Mint — First 5,000 wallets claim 1,000 $EGG each - EGG Staking — Stake $EGG to earn 5% of all harvest revenue, paid in MOTO (real yield from real protocol activity) - EGG Boost — Lock $EGG in The Pan to increase your Cook Level multiplier - LP Mining — Provide EGG-MOTO liquidity to earn $EGG emissions over ~12 months The flywheel: yield and fees create visible APY, which attracts deposits, which generates more yield and fees. Unlike most yield farms that rely solely on token emissions, Scramble is built on three engines — external farming yield, Yoke Tax fees, and time-limited $EGG emissions. The first two are permanent and generate real yield long after launch incentives expire.
FLIP GAME
Flip Game is a simple, on-chain coin flip game on OPNet. You pick heads or tails, choose your token (PILL or MOTO), place a bet, and flip. Win and you double your bet; lose and the house keeps it. The game runs as a smart contract on Bitcoin Layer 1 via OPNet. All flips are verifiable on-chain. Connect your wallet (OP_WALLET) to play on OPNETTESTNET
BitLaunch
by JonathanNo-Code DeFi Launchpad on Bitcoin L1. Token Launch, Presale, Vesting, Liquidity Lock & Airdrop built on OPNet
OPNet Hub
by OPHUBOPNet Hub is the first all-in-one mission control for the OP_NET consensus layer on Bitcoin L1. It combines live on-chain data (block height, epoch progress, gas, real BTC balance via OP_NET RPC), a Token Launcher with real OP-20 deploy flow, a DEX interface powered by Motoswap, an Epoch Miner idle game with $MINE tokenomics (halving, leaderboard, claim flow), a Quest system for onboarding builders, and a directory of 26+ OP_NET dApps — all in one app. Two OP-20 tokens ($MINE, $VIBE) deployed on testnet, verified on-chain with ML-DSA signatures.
BAMPL
![](data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" width="399" height="399"><rect fill-opacity="0"/></svg>)
by Danny BuidlviewAmpleforth-style elastic supply token on Bitcoin L1. BAMPL automatically expands supply when price exceeds target and contracts when below, keeping every holder's percentage ownership constant. Features a live dashboard showing real-time rebase events, supply changes, price tracking with sparkline charts, and a built-in faucet that distributes 1,000 BAMPL to any connected wallet. The first elastic supply / rebasing token ever built on Bitcoin.
