For a user of an on-chain reputation protocol, which token is used to attest to skills or credentials?

In on-chain reputation and identity protocols, skills and credentials are most commonly attested to using Soulbound Tokens (SBTs) or Attestations:

• Soulbound Tokens (SBTs): These are non-fungible, non-transferable digital tokens permanently bound to a specific wallet address or decentralized identifier (DID). Because they cannot be transferred or sold, they function well as immutable achievement badges, completion certificates, or academic/professional credentials.
• Attestations (e.g., via Ethereum Attestation Service - EAS): Rather than minting a distinct token, many modern reputation frameworks rely on cryptographic attestations. An attestation is a signed, verifiable statement (anchored on-chain or stored off-chain with an on-chain reference) made by an issuer—such as a protocol, DAO, or peer—confirming a user’s specific skill, score, or credential without needing a traditional token.

If you are looking at a specific protocol (like Talent Protocol, Guild.xyz, or EAS), let me know and I can give you the exact primitive or schema format they use!

If you mean Ethereum Attestation Service (EAS), there isn't a dedicated token used to attest skills or credentials. The attestation itself is the credential record—a cryptographically signed claim that can be stored on-chain or off-chain.

If you're referring to a specific reputation protocol/token (rather than EAS), tell me the protocol name and I can identify its token.

The token is $WHUF, the native token of Ethos, an on-chain reputation protocol. It is used for vouches, reviews, attestations, and related reputation actions; vouches are specifically staked in $WHUF.

If you meant Ethereum Attestation Service (EAS), there isn't a dedicated EAS token—the attestation itself is the credential record.

In on-chain reputation and identity ecosystems, skills or credentials are most commonly attested to using one of two primary token/cryptographic primitives:

• Soulbound Token (SBT): A specialized, non-transferable Non-Fungible Token (NFT) permanently bound to a specific wallet address. Prominent standards like ERC-5114 (for badges) or ERC-5484 (consent-based SBTs) are explicitly used to represent academic degrees, work history, professional licenses, and skill certifications. Because they cannot be sold or transferred, they accurately reflect a person's immutable digital resume.
• On-Chain Attestation: Rather than a traditional token minted directly to a wallet, many modern protocols utilize raw cryptographic attestations (such as those via the Ethereum Attestation Service or similar schema registries). These write a verified statement or claim directly to the ledger linked to a user’s address without necessarily requiring a standard token wrapper.

If you have a specific protocol in mind (like EAS, Gitcoin Passport, or Talent Protocol), let me know and I can give you the exact schema or token type they use.

The answer is Ethereum Attestation Service (EAS)—but technically, EAS does not use a token to attest skills or credentials. It uses on-chain attestations, which are signed, verifiable credential records.

If you meant a tokenized credential specifically, the common term is a Soulbound Token (SBT): a non-transferable token that can represent skill attestations or other reputation credentials.

So, in short: EAS attestation, not an EAS token; SBT if you're asking about a token representing the credential.

In on-chain reputation and identity protocols, skills, achievements, and credentials are typically attested to using one of two primary types of tokens or cryptographic records:

• Soulbound Tokens (SBTs): These are non-transferable, publicly verifiable NFTs permanently bound to a specific user's wallet address. Because they cannot be bought, sold, or transferred, they are widely used to represent formal credentials, course completions, attendance badges, or verified skill milestones.
• Attestations / Verifiable Credentials (VCs): Rather than standard minted tokens, many modern protocols (like the Ethereum Attestation Service ) use lightweight, cryptographically signed data statements called attestations . An issuer signs a structured claim (based on a predefined schema) affirming a user's skill or credential. These can live directly on-chain or off-chain while remaining cryptographically verifiable on-demand.

If you have a specific protocol in mind (like EAS, Gitcoin Passport , or Guild.xyz ), let me know and I can detail how it structures and verifies those specific credentials.

A Soulbound Token (SBT) or a Verifiable Credential (VC) is typically used to attest to skills, credentials, or identity claims on-chain.

• Soulbound Token (SBT) : A non-transferable, public digital token that represents a person's traits, credentials, and affiliations. Because they cannot be bought, sold, or transferred to another wallet, they permanently bind a skill or credential to a user's decentralized identity.
• Verifiable Credential (VC) : A cryptographically secure digital record that proves a specific claim (such as a degree, certification, or completed course) issued by a trusted party and tied to a decentralized identifier.
• Attestation : Protocols like the Ethereum Attestation Service also allow issuers to record structured, signed claims directly on-chain or off-chain without necessarily needing a standard token wrapper.

If you'd like, let me know:

• Which blockchain network you are building on or using
• Whether you need a transferable or non-transferable credential format

I can recommend a specific protocol or standard for your use case.

The token is $TALENT, the native token of Talent Protocol. It powers Talent Protocol’s on-chain reputation ecosystem, where Skills Credentials attest to specific expertise and achievements.

So the answer is: $TALENT.

In on-chain reputation and identity protocols, the primary token or data structure used to attest to skills, achievements, or credentials is the Soulbound Token (SBT) or a cryptographic Attestation.

Depending on the specific architecture of the reputation protocol, this is handled via two main formats:

• Soulbound Tokens (SBTs): These are non-fungible, non-transferable tokens permanently tied to a user's wallet address (their "soul"). Because they cannot be sold, traded, or transferred to someone else, they function as an on-chain digital resume or CV—ideal for representing academic degrees, professional certifications, work history, and skill badges.
• Attestations (e.g., via Ethereum Attestation Service - EAS): Rather than deploying a full token contract, many modern on-chain reputation systems use lightweight cryptographic statements called Attestations . An issuer (like a university, employer, or peer) signs a structured data claim verifying a user's credential. These can live on-chain or off-chain while remaining cryptographically verifiable by any third-party app.

If you are looking for a specific protocol (such as EAS, Gitcoin Passport, or Semaphore), let me know and I can dive deeper into how they structure their credentials!

The token is TALENT, the native token of Talent Protocol. Talent Protocol uses its Talent Passport to aggregate verifiable skills, credentials, achievements, and professional reputation on-chain.

So, if the question is specifically asking for the token associated with an on-chain professional reputation protocol for attesting to skills or credentials, the answer is TALENT. citeturn0search6
