Shytoshi Kusama Silent on X Since May 13 as Shibarium Speculation Builds

Silent since May 13

Shytoshi Kusama, lead developer of the Shiba Inu ecosystem, has not posted or interacted publicly on X since May 13, 2026, and in that stretch his profile page has become the community's most-read signal source. With no statements coming from the account, members of the Shiba Inu community parse the smallest traces he leaves behind, and the most recent trace landed in September 2026. That month Kusama updated the biography field on his X profile to a single word, “Polish”, and changed the location field to “Close”.

The edits amount to two words, and they have carried a disproportionate share of interpretation. Community members read them as evidence that a project under Kusama's direction may be approaching its completion stage, on the theory that a developer preparing an announcement would first stage his public profile. That reading has one clear weakness: Kusama has never confirmed what the changes refer to. He has not said whether “Polish” points to work inside Shiba Inu, to the independent artificial intelligence initiative he is associated with, or to a separate effort altogether, and his continued absence from the platform keeps all three possibilities open. Until he speaks, every interpretation of the profile remains unconfirmed.

The pattern matters because of Kusama's role. As the ecosystem's lead developer, his account has historically been the channel through which direction on Shiba Inu's technical roadmap reached the public. When that channel goes quiet, the community has no substitute for it, which is why a two-word biography edit in September can draw more discussion than a routine code deployment. The record currently stands as follows: no posts, no replies and no visible activity since May 13, 2026, one bio reading “Polish”, one location reading “Close”, and no statement connecting either to a named project.

Shibarium rebuild advances

While the ecosystem's lead developer stays off the platform, the technical side of Shiba Inu has kept moving. Community figure Mazrael relayed a message from developer Kaal Dhairya confirming that the reorganization problem on Shibarium has been solved, and that the only remaining step in the migration to the new environment is DRPC completing the same transition on its side. A reorg, in which recent blocks get replaced and transactions reorder, counts among the more disruptive faults a layer 2 network can hit, which is why its resolution was flagged first. In his latest assessment on X, Mazrael described Shibarium as still operating in rebuild mode, while noting that new features and various improvements have shipped quietly on the network in recent weeks.

The list behind that description is specific. CreateX, a standard factory tool that lets developers deploy their contracts at the same address on every chain, is now available for use on Shibarium. All 12 contracts covered by Safe v1.4.1 have been deployed to their canonical addresses through the Safe Singleton Factory. The x402 system is fully active on the network, which opens the way for automated agents, including AI trading bot implementations, to settle payments in SHIB, TREAT or wrapped BONE.

Infrastructure work extends beyond contracts. DRPC refers to the remote procedure call infrastructure that lets decentralized applications connect to blockchain networks, while RPC is the basic connection layer for sending data to and from a network's nodes. The Shibarium RPC registration has been renewed in the Ethereum lists/chains registry, and up-to-date connection details are accessible through Chainlist. In September 2026, the official SHIB website and the ShibaSwap page moved to Cloudflare infrastructure, both platforms gained IPv6 support, and the old hosting setup was retired. None of those steps requires Kusama's voice, which is why the two tracks have diverged.

Of the two threads in this story, only one can be verified from outside. Kusama's profile edits are words on a profile page with no statement attached, and they stay speculation until he chooses to explain them. The Shibarium work is different: contract deployments, the renewed registry entry and the x402 activation are all checkable, and each one narrows the gap between the network and production-grade infrastructure. By wiring agent payments in SHIB, TREAT and wrapped BONE, x402 ties Shibarium's payment activity to the ecosystem's tokenomics and places the network closer to the PayFi segment, where machines settle value directly. The nearest fixed point ahead is the DRPC transition, the one item developers still list as open; until it completes, Shibarium formally remains in rebuild mode.
