Binance listed TerraUSD as LUNA briefly crossed $100

Binance opened spot trading in TerraUSD (UST) at 08:00 UTC on December 24, 2021, adding UST/BTC, UST/BUSD and UST/USDT markets. The exchange’s dated notice also said deposits were already available and estimated that withdrawals would open at 08:00 UTC on December 25. It was a concrete distribution milestone for Terra’s dollar-targeting stablecoin at the moment the network’s LUNA token briefly traded above $100 and the dollar value attributed to Terra decentralized-finance positions reached a record.

The listing mattered because it placed UST directly against bitcoin and two large centralized-exchange dollar tokens on Binance. That reduced the number of conversions needed for Binance customers seeking UST exposure, but it did not validate UST’s peg design, guarantee redemption at one dollar, or make Binance the issuer.

What the December 24 record establishes

Binance described UST as a decentralized algorithmic stablecoin on the Terra blockchain. Its notice said that minting one UST required burning one dollar’s worth of LUNA. That was the exchange’s contemporaneous description of the mechanism, not an independent audit of reserves or a finding about how the system would perform under stress. Binance also listed Spell Token in the same notice, but UST’s integration was the development with broader implications for Terra’s monetary design and market access.

Contemporaneous CoinDesk reporting placed LUNA above $100 during European trading hours on December 24 after it had fallen to roughly $85 on December 23. CoinDesk said the token met resistance near $100 and was five cents below that level at its reporting cutoff. Because crypto trades continuously across fragmented venues, that observation is an intraday market reading, not a universal closing price.

CoinMarketCap’s December 24 historical snapshot gives a separate end-of-snapshot view: LUNA at $95.97, a $35.07 billion market capitalization, $3.89 billion in trailing-24-hour volume, a 2.26% 24-hour gain and a 46.05% seven-day gain. Those percentages use CoinMarketCap’s snapshot and aggregation methodology; they should not be treated as returns from a regulated closing auction. The difference between the $100 intraday report and the $95.97 snapshot illustrates the importance of the measurement window.

DeFi growth supplied the institutional context

CoinDesk, citing DeFi Llama, reported that Terra’s total value locked crossed $21 billion on December 24, up from about $18 billion on December 22. More than $9 billion was attributed to Anchor, while TerraSwap exceeded $2 billion. The report counted 13 Terra protocols and ranked the network second to Ethereum by that metric.

“Total value locked” was a dashboard estimate, not audited client assets or cash held in custody. Its dollar value could rise because token prices rose, because users deposited more tokens, or both. Cross-chain comparisons also depended on DeFi Llama’s protocol coverage and classification choices. The figures therefore established rapid measured expansion, not the quality, liquidity or safety of every position included.

Why it mattered — and what remained unknown

December 24 joined two reinforcing developments: centralized distribution for UST and a sharp repricing of LUNA alongside expanding DeFi measurements. The defensible interpretation on that date was that Terra had become a major stablecoin and DeFi contender. It was not yet possible to infer durable peg stability, sustainable yields or resilience during mass redemptions from a listing announcement, token price, or TVL leaderboard.

The essential follow-up questions were whether UST could hold its target across venues during volatility, how much market depth the new Binance pairs would develop, and whether Terra’s applications could retain deposits without relying on rising token prices. Those uncertainties belonged in the December 24 record even while the market signals were strongly favorable.
