JustCryptos is the JUST ecosystem's cross-chain wrapping layer on TRON — Poloniex-custodied 1:1 representations of BTC, ETH, LTC, DOGE and other premium assets minted as TRC-20 tokens (BTCT, JSTBTC, JSTETH, …) so they can circulate inside JustLend and SunSwap.
Native BTC/ETH/LTC/DOGE are locked with the Poloniex custodian; an equal amount of TRC-20 wrapped tokens is minted on TRON. Supply always mirrors reserves 1:1.
Proof-of-lock invariant: reserves published on Poloniex must always equal the TRC-20 supply on TronScan. Backing is 100% by construction — but it rests entirely on one centralized custodian honoring redemptions.

TRON-native DeFi (JustLend, SunSwap) had no liquid representation of premium external assets such as BTC, ETH, LTC and DOGE, limiting the collateral and trading pairs available on TRON.
JustCryptos mints 1:1 TRC-20 wrapped tokens (BTCT, JSTBTC, JSTETH, JSTLTC, JSTDOGE) backed by native-asset reserves custodied at Poloniex, with the proof-of-lock published as `Native Treasury` and `TRC-20 Supply` counters.
Among bridges, JustCryptos's largest market is the TRON-side wBTC equivalent (BTCT) — the dominant on-TRON Bitcoin representation, integrated natively across the JUST ecosystem (JustLend collateral, SunSwap pools).
