Release notes

Latest product and developer changes

Latest changes to the Radius Network. New features, improvements and bug fixes will be posted here.

2026-05-11 (0d56ee4e)

Improvements

  • Lower Turnstile minimum transaction size: The minimum amount of SBC required to trigger a Turnstile gas conversion has been reduced tenfold — from 0.10 SBC to 0.01 SBC per execution. Wallets with small token balances can now participate in transactions that previously required a larger deposit. The 10.0 SBC per-transaction ceiling is unchanged.

  • More accurate balance reporting: eth_getBalance now returns your full SBC token holdings converted to native currency, with no artificial ceiling. Previously the reported balance was capped at the per-transaction execution limit; now wallets with larger holdings see their true total displayed in block explorers and wallets. Note that the per-transaction spending limit remains in effect — the displayed balance may exceed what can be spent in a single transaction.

API / RPC changes

eth_getBalance — semantics change

  • Before: Balance was floored to the nearest minimum debit unit and capped at the maximum per-transaction backfill amount.
  • After: token_balance × per_unit_exchange_rate + raw_native — no floor rounding, no cap.

Affected clients: Any client that uses eth_getBalance to predict whether a transaction will succeed based on comparing the balance to the transaction value. The returned balance may now be higher than what the network will actually provision for a single transaction. Use eth_estimateGas to validate that a specific transaction will succeed before submitting.

Improvements

  • Internal stability and reliability improvements.

2026-04-15 (7b8a282a)

Improvements

  • eth_sendRawTransaction now queues transactions rejected with NonceTooHigh in a per-sender pending transaction pool and retries them automatically in a background clearout loop. The pool supports up to 30 queued transactions per sender across up to 100 addresses. Replace-by-fee is supported.
  • eth_sendRawTransactionSync now returns EIP-7966 error code 6 with the expected nonce on nonce gaps, avoiding an extra eth_getTransactionCount round-trip.
  • eth_call dry-runs now skip balance validation unconditionally.

BREAKING CHANGES

  • The Mainnet Chain ID has been updated from 723 to 723487.

New features

  • Method requests referring to old states will now return an error. Radius does not store historical state and such requests succeeding may be misleading. Note: block numbers within the last 1000 seconds will be treated as "current" for tooling compatibility.
  • Supports eth_maxPriorityFeePerGas.

Improvements

  • Internal Performance Improvements

Bug Fixes

  • Logs in receipts will correctly populate block hash, block number and transaction index.
  • Return null instead of 0x0 for the to field in contract creation transaction receipts.
  • Return null for invalid block hashes, in requests to eth_getBlockByHash.

2026-03-26 (89b06f15)

New features

  • Support for eth_sendRawTransactionSync
  • You can now trigger the turnstile by sending gas tokens directly, rather than just allowin the turnstile to cover gas fees.
    • E.g. cast send --value 0.1ether ... will trigger the turnstile if you do not have enough gas tokens to cover the transaction, up to a limit of 10 RUSD.

Improvements

  • Internal Performance Improvements

Bug fixes

  • Fixes a bug where in some cases receipt requests would return the incorrect receipt. This occurred in cases of very high load on transactions involving conflicting state.
