TRON DeFi approvals
How TRON DeFi venues request TRC20 approvals, why unlimited is common on SunSwap and JustLend, and how to audit leftover router allowances.
DeFi without custody still needs allowance
Non-custodial routers never hold your seed, but they must pull tokens to swap or collateralize. That pull is transferFrom under an allowance you signed. DeFi safety starts with knowing which routers still have that right.
This desk is the inventory. It is not a yield product.
Unlimited is a UX default, not a verdict
SunSwap and JustLend-style UIs often request max uint256. Seeing unlimited next to those names is expected. Seeing unlimited next to a random hex is not.
Filter Unlimited, then read the name column before you panic-revoke your active trading stack.
Old venues linger
Migrated routers leave old spender approvals behind. problem-old-dex covers that. If you do not use the venue, zero the slot even if the name looks familiar.
Each TRC20 has its own slot — USDT, TUSD, and others revoke separately.
What this desk will not do
We will not auto-revoke a DeFi stack, promise APY, or ask for a seed to “sync positions.” Deep scan is read-only ~2–3 TRX.
Independent — not SunSwap, not JustLend, not TRON Foundation.
Operational habit
After any new DeFi connect, re-paste your T-address here. Keep a short allowlist of spenders you recognize. @wholetron for public hex checks.
