What Is Sign (SIGN) and How Does It Work?
Sign (SIGN) is the native token of the Sign ecosystem, which aims to create a global verification layer for digital information through two flagship offerings:
TokenTable, a
smart-contract-powered dashboard for transparent token distributions and airdrops, and
Sign Protocol, an omni-chain attestation network that lets anyone issue and verify
cryptographic attestations of claims or data points across multiple blockchains.
Under the hood, Sign Protocol lets developers define
Schemas that structure the data to be attested. When a user or application creates an
Attestation, it’s digitally signed and anchored on supported chains (
Ethereum,
TON,
Solana, etc.), making it publicly verifiable at any time. The
SIGN token powers this process: holders use it to pay on-chain fees for writing attestations,
stake or reward network participants who validate attestations, and vote on protocol upgrades and parameter changes, ensuring a decentralized, community-driven verification system.
Who Founded Sign Protocol and When Was It Officially Launched?
Sign Protocol traces its roots back to the EthSign project, which first debuted as a blockchain‐based document signing tool in Q3 2021. In early 2024, the team rebranded and officially launched the omni-chain attestation service as Sign Protocol. The project is led by co-founders Xin Yan (CEO), who sets the strategic vision, and Jack X (CTO), a blockchain veteran and former USC lecturer.
After several beta releases (TokenTable in 2023) and strategic partnerships, Sign Protocol’s
mainnet went live in
Q1 2024, marking its first fully decentralized release under the SIGN brand.
Sign Protocol Roadmap
Looking ahead, Sign Protocol plans to roll out:
• Q1 2025: Cross-chain attestation support and integration with major blockchains
• Q2 2025: Expanded network integrations and an upgraded schema registry for more flexible attestations
• Q3 2025: Launch of developer SDKs/APIs and a user-friendly attestation creation dashboard
What Are the Primary Use Cases of SIGN Token?
SIGN is required to pay for on-chain attestations and TokenTable distributions, covering
gas and service fees across multiple blockchains. It also underpins Sign Protocol’s security and governance: holders stake SIGN to reward or run attestor nodes and participate in token-weighted voting for protocol upgrades.
On BingX, log in to your account, select the “
Spot” market, search for the
SIGN/USDT trading pair, and choose a
market or limit order to buy or sell SIGN based on your target price and amount. Once your order fills, your new SIGN tokens will appear in your Spot Wallet instantly.
What Is Sign Protocol Tokenomics?
Sign (SIGN) has a fixed
total supply of 10 000 000 000 tokens, all minted on the Ethereum mainnet and bridged to
BNB Chain and Base for cross-chain compatibility. At its TGE on
April 28, 2025,
1 200 000 000 SIGN (12 % of the total) will enter circulation, where it will power on-chain attestations, governance, and TokenTable distributions across the Sign ecosystem.
The 10 billion tokens are allocated to align stakeholder incentives and community growth:
1. 40% (4 billion) for community incentives, including a
10% TGE airdrop and
30% reserved for future rewards and unlocks
2. 20% (2 billion) to early backers and investors
3. 10% (1 billion) to the founding team
4. 10% (1 billion) to the Sign Foundation
5. 10% (1 billion) for ecosystem development initiatives
Allocated tokens (outside the TGE airdrop) vest over time under configurable on-chain schedules to ensure market stability and long-term alignment.
How to Claim SIGN Airdrop
The SIGN airdrop is Sign Protocol’s token distribution event that rewards early adopters, developers, and community contributors by allocating SIGN tokens to qualifying
wallets. Eligible participants include OG EthSign users, schema creators who published attestations by the snapshot date, early TokenTable distribution or beta airdrop participants, and active community members on Discord, Telegram, or Twitter who completed engagement tasks.
How to Participate in Sign Protocol Airdrop
1. Hold & Qualify: Ensure you control an
EVM-compatible wallet (e.g.
MetaMask) that meets at least one of the criteria above as of the
April 25, 2025 @ 12:00 UTC snapshot.
2. Connect Wallet: Visit airdrop.sign.global and click Connect Wallet to link your address.
3. Verify Eligibility: Hit Check Eligibility. The portal will reference the snapshot and display your allocated SIGN amount .
4. Complete KYC (If Prompted): Some tiers require basic identity verification via Sumsub before claiming.
5. Claim $SIGN Tokens: Click Claim and approve the on-chain transaction to receive your tokens directly in your wallet. Claims open exactly when SIGN trading goes live on April 28, be ready to connect and claim instantly.
Once claimed, you can trade SIGN on BingX’s Spot market under the SIGN/USDT pair via market or limit orders.
Which Blockchain Does Sign Protocol Operate On?
Sign Protocol is an omni-chain attestation network built on Ethereum and a broad set of EVM-compatible chains, with SIGN issued as an
ERC-20 token on Ethereum and bridged to
Arbitrum One, Base, BNB Chain,
Celo, Cyber, Degen,
Gnosis, OKX X Layer, opBNB,
Optimism,
Polygon,
Scroll, and
ZetaChain, ensuring you can create and verify attestations wherever your project requires.
Which Wallets Support SiGN Tokens?
Because SIGN is issued as an ERC-20 token on Ethereum and bridged to multiple EVM-compatible chains,
any wallet that supports ERC-20 tokens can hold SIGN. Popular choices include
MetaMask (Web/Mobile) and
Trust Wallet (Mobile) , both of which let you easily add custom tokens like SIGN by pasting its contract address.
Beyond those, leading software wallets such as
Coinbase Wallet,
Rainbow,
Argent,
imToken, and
TokenPocket all support Ethereum-based assets out of the box. For maximum security, you can also store SIGN on hardware devices like
Ledger (via Ledger Live) and
Trezor (via Trezor Suite). To manage SIGN on bridged chains (Arbitrum, BNB Chain, Base, etc.), simply switch your wallet’s network to the desired chain and import SIGN as a custom token.
What Makes SIGN Crypto a Good Investment?
Sign Protocol delivers real-world utility by powering omni-chain attestations and secure token distributions through its TokenTable dashboard, enabling enterprises and developers to create, verify, and manage transparent on-chain claims across Ethereum, EVM-compatible chains, Solana, TON, and beyond, driving demand as SIGN is used to pay fees, stake for network security, and govern protocol upgrades.
On the investment side, Sign Protocol boasts a $16 million strategic backing from Binance’s YZi Labs (led by CZ) and confirmed listings on top exchanges like Binance and Bybit ahead of its April 28 airdrop, ensuring strong liquidity and visibility. Coupled with disciplined tokenomics, only 12% of its 10 billion supply entering circulation at launch and the rest vested over time, SIGN offers investors a compelling balance of utility, institutional support, and long-term alignment.
