Harmonic Protocol

1/ Harmonic Protocol runs through x402 requests, signed trade messages that enter a shared public mempool on @base Each request can be picked and executed by any human validator, replacing automated miners with real participants.

Human-validated. 41,648 USDC have been tipped through the dApp. $HARMO scan: #readContract#F32" target="_blank" rel="nofollow noopener">basescan.org/address/0x6846…

@LUO4562580 @0xronova Please refer to the thread we wrote: x.com/harmonicprtc/s…

@0xronova @harmonicprtc Can you explain this?

Liquidity is locked. $HARMO x402, but human-validated. app.uncx.network/lockers/univ2/…

600 USDC by solving CAPTCHA. How to become a $HARMO validator: Every transaction on the Harmonic dApp includes a tip, set by the user submitting the swap (minimum 1 USDC) All requests enter the public mempool, protected by CAPTCHA to prevent bots Any user can access this mempool and become a validator by solving the CAPTCHA and executing pending requests A fully open, human-validated execution layer. Become a validator here at harmo.pro/mempool

$HARMO mint is live It will remain open until it reaches 100,000 USDC. Mint here: harmo.pro/mint

Thanks @harmonicprtc 1350 $USDC BY SOLVING 5 CAPTCHA

@bajacamalu Your tx simply failed. In that case, we don't charge USDC.

@harmonicprtc Pending now its lose?

SOLD OUT IN 9 MIN. 🎉 $HARMO is now live on dexscreener: dexscreener.com/base/0xbca3ecd…

Most x402 projects use EIP-3009 TransferWithAuthorization function: any address can execute the authorization, and the transfer goes through as long as the signature is valid. $HARMO uses ReceiveWithAuthorization function instead, meaning: - only the receiving address can execute the order - the protocol controls execution - once the mint is sold out, execution becomes impossible - no "late" USDC transfers slipping through Other mints (including $PING) could still receive USDC after selling out because execution relied on TransferWithAuthorization With ReceiveWithAuthorization, that can’t happen. With $HARMO, sold out means sold out. More details on EIP-3009: eips.ethereum.org/EIPS/eip-3009

@richirokez The screenshot came from that test phase, it’s still visible in the interface for us We updated the thread.

🧵 Minting Phase Overview 1/ At launch, Harmonic introduces a minting phase capped at 100,000 USDC, representing 66% of the total supply (66,000,000 $HARMO).

If users choose not to trade through the dApp, a 4% swap fee applies This differential is designed to encourage trading through the human-validated flow, where $HARMO is executed as intended.

6/ Users will be able to trade $HARMO directly through the dApp, as well as on Uniswap in the usual way. On the dApp, a 1% fee is applied to every transaction These fees go directly to the human validators operating the $HARMO layer.
