Polygon also said the rollout already supports deployment on the Ethereum mainnet. The launch points to Polygon’s push to serve institutional blockchain use cases with infrastructure that combines private network deployment and access to broader onchain connectivity.100
Miden2026-09-14 15:24:47Miden rolls out final major testnet release before mainnet, adds network feesPrivacy-focused blockchain Miden has released testnet v0.16, describing it as the last major testnet version before mainnet launch. The update introduces network fees on the testnet for the first time, with a typical transaction costing about one-hundredth of a cent. Once the mainnet goes live, those fees will be denominated in USDCx. Beyond pricing changes, v0.16 adds encrypted submission for private transaction inputs and streamlines the multisignature flow. Miden also reduced the production build size of its Web SDK from 27.4 MB to 18.8 MB, a change aimed at improving the developer experience. The release includes updates to native token swaps as well, letting users set a minimum accepted amount and a minimum fill size to avoid dust-level partial fills. Miden said Agglayer and Epoch integrations are now ready and available for testing on the testnet.1160
