TRON processed $167 billion in stablecoin transfers on June 21, 2026, a single-day network record, while its TRC-20 USDT supply had reached an all-time high of $86.7 billion in late April, putting TRON ahead of Ethereum as the largest USDT chain, according to CryptoNinjas and Crypto News.
The June 21 session cleared 10.6 million transactions. The 30-day transaction average as of that date was 12.81 million per day, up 8.54% from the prior 30-day period, according to CryptoNinjas.
TRON's volume record
Transaction count and dollar volume did not peak on the same day. TRON set its all-time daily transaction high of 14.3 million on June 10, 2026, confirmed by TronScan and announced by founder Justin Sun. The June 21 session had fewer transactions but a higher dollar total.
That split points to larger average transfers on June 21, rather than a wider spread of smaller payments.
USDT supply lead
The volume record sits on a USDT supply base that already made TRON the dominant dollar-stablecoin rail. TRC-20 USDT supply hit an all-time high of $86.7 billion on April 21, 2026, giving TRON just over 46% of total USDT outstanding, the largest share held by any chain, against a total USDT market of roughly $187.96 billion at that time, per Crypto News.
Cost is the main structural reason. TRON charges under $0.01 per transaction and sustains more than 2,000 transactions per second.
Peer check
The peer picture for June 21 is incomplete. The most recent comparable baseline for Solana is February 2026, when the network processed $650 billion in total monthly stablecoin volume, a record at the time, equivalent to a daily average of roughly $23 billion, according to a March 2026 report.
Direct stablecoin volume data for Solana and Sui on June 21, 2026, was not available from sources verified for this article. Against the last published Solana benchmark, TRON's June 21 figure was more than seven times that daily average.
