SUN.io, a TRON-based DeFi platform, has announced a crucial upgrade to its Smart Router. In this respect, SUN.io is introducing Permit2 and Universal on the Smart Router to improve the on-chain trading within the TRON network. As the platform revealed in its official press release, the new upgrade bolsters transfer efficiency while also fortifying authorization security to benefit consumers. Additionally, with the integration of cutting-edge approval and routing mechanisms, the platform attempts to offer seamless DeFi interactions within an optimized, unified framework.

New SUN.io Smart Router Upgrade Unveils Universal Router for Effective DeFi Trading

The new Smart Router upgrade of SUN.io takes into account the introduction of Permit2 and Universal Router. The development reaffirms the platform’s commitment to delivering secure and seamless trading experience in the TRON ecosystem. Particularly, Universal Router serves as an inclusive instruction interpreter in the case of swaps.

The router permits liquidity aggregation across diverse pools, taking into account SunSwap V1, V2, V3, and Curve, HTX-SUN, and PSM within one transfer. With this, the traders can leverage better execution and deeper liquidity without requiring individual interaction with each of the protocols. Along with that, by accumulating logic within one transfer, the Universal Router minimizes operational complexity while also increasing capital efficiency.

Additionally, it also decreases friction for advanced and retail consumers who frequently shift liquidity across diverse pools. Moreover, this combined routing approach attempts to notably improve trading efficiency in addition to decreasing overall transfer overhead within the TRON ecosystem. Parallel to Universal Router, SUN.io is also bringing forth the Permit2 protocol that modernizes token authorization. It permits the consumers to effectively grant a high-allowance authorization for one contract once. Subsequently, they can reuse it across diverse interactions multiple times, removing the need for recurrent approval transfers.

Accelerating Efficiency and Security to Streamline On-Chain Trading

According to SUN.io, the exclusive upgrade also pays significant attention to security. So, Permit2 offers a dual risk management apparatus in line with both amount and time. The protocol utilizes deadlines for signature expiration and allowance limits to prevent likely misuse even in the case of a compromised authorization. Ultimately, the latest Smart Router upgrade of the platform is poised to offer a relatively user-friendly and robust on-chain trading setting.

Fed Decides On Interest Rates Today—Here’s What To Watch For

The post Fed Decides On Interest Rates Today—Here’s What To Watch For appeared on BitcoinEthereumNews.com. Topline The Federal Reserve on Wednesday will conclude a two-day policymaking meeting and release a decision on whether to lower interest rates—following months of pressure and criticism from President Donald Trump—and potentially signal whether additional cuts are on the way. President Donald Trump has urged the central bank to “CUT INTEREST RATES, NOW, AND BIGGER” than they might plan to. Getty Images Key Facts The central bank is poised to cut interest rates by at least a quarter-point, down from the 4.25% to 4.5% range where they have been held since December to between 4% and 4.25%, as Wall Street has placed 100% odds of a rate cut, according to CME’s FedWatch, with higher odds (94%) on a quarter-point cut than a half-point (6%) reduction. Fed governors Christopher Waller and Michelle Bowman, both Trump appointees, voted in July for a quarter-point reduction to rates, and they may dissent again in favor of a large cut alongside Stephen Miran, Trump’s Council of Economic Advisers’ chair, who was sworn in at the meeting’s start on Tuesday. It’s unclear whether other policymakers, including Kansas City Fed President Jeffrey Schmid and St. Louis Fed President Alberto Musalem, will favor larger cuts or opt for no reduction. Fed Chair Jerome Powell said in his Jackson Hole, Wyoming, address last month the central bank would likely consider a looser monetary policy, noting the “shifting balance of risks” on the U.S. economy “may warrant adjusting our policy stance.” David Mericle, an economist for Goldman Sachs, wrote in a note the “key question” for the Fed’s meeting is whether policymakers signal “this is likely the first in a series of consecutive cuts” as the central bank is anticipated to “acknowledge the softening in the labor market,” though they may not “nod to an October cut.” Mericle said he…
