On-chain credit systems won’t fully replace traditional ones soon, but will coexist and gradually erode them. Blockchain offers transparent, immutable, permissionless scores (e.g. Spectral, Cred Protocol), cutting costs and enabling underbanked access. Traditional FICO/ECL systems still dominate lending, regulation and institutional trust. In 5-10 years, DeFi and hybrid models may handle 20-40% of global credit for individuals and SMEs.Key projects: https://spectral.finance https://credprotocol.com https://arcx.money https://tryprisma.com

How to spot a disguised rug-pull DeFi project:Check if liquidity is locked (rugdoc.io or tokensniffer.com) – unlocked = instant rug risk. Contract ownership renounced? If dev still holds mint/upgrade rights → dangerous. 90%+ tokens in dev/snipers wallets + fake distributed holders = classic honeypot. Anonymous team with stock photos + no audit or fake Certik badge = red flag. Insane APY (10,000%+) with tiny liquidity pool = unsustainable ponzi. Use honeypot.is checker before aping.
