They call this the #CEXyDEX.

Crypto has long split between ease of using centralized exchanges vs self-custody and transparency of DeFi. P2P.me, an on-chain protocol on Base, has been has been trying to bridge the gap by creating decentralized ramps between fiat and crypto. And now the team is taking the next step with Coins.me, a consumer app that makes using crypto feel as simple as UPI or PIX.

A Network Built on Decentralization and Trust

P2P.me in itself enables instant, private swaps between USDC and local fiat by connecting verified liquidity providers and users via smart contract order matching. Each order is peer-to-peer, with fiat settlements verified using zero-knowledge proofs (ZKPs), so transactions clear in under 90 seconds without exposing personal data. Order books, dispute resolution, and reputation all run on-chain, rewarding good actors and penalizing fraud. The design removes custodial risk and central intermediaries while maintaining reliability.

Backed by Coinbase Ventures and Multicoin Capital (co-leading a $2M seed round in April 2025), P2P.me is moving from infrastructure to consumer experience with Coins.me.

The Foundation: Base + On-Chain Ramps

Built on Base, P2P.me has been redefining fiat–crypto movement with on-chain speed and simplicity.

Public Dune data shows steady 2025 growth in volume, active wallets, and transactions in the p2pme protocol. Highlights include:

  • Consistent MoM volume growth in India and Brazil, reaching $13.9M as of this writing.
  • Average settlement under 90 seconds, validating real-time efficiency.
  • Repeat usage by verified liquidity providers, indicating network trust and stability.

These signals suggest Coins.me launches as an evolution of a protocol already serving real demand.

As of October 2025, the network has processed $13.9M across 165,263 completed orders from 19,123 unique users, with $2.06M in October month-to-date—averaging roughly $100K per day.

Introducing Coins.me

Coins.me is a simple self-custodial DEX that allows users, old or new, to one-tap buy into the top cryptocurrencies in the world. It removes gas friction and simplifies on-chain swaps. Powered by Uniswap V3 under the hood, it delivers CEX-like ease while staying fully decentralized.

Key features:

  • One-tap login: Google, phone, or passkey. A smart wallet on Base is created automatically—no seed phrases, still self-custodial.
  • Gas-free swaps: Network fees are sponsored, so users don’t juggle gas or pop-ups for multiple allowance transactions.
  • Fast in-built ramps: At launch, users in India, Brazil, and Indonesia can buy or sell via UPI, PIX, or QRIS. More countries are planned to launch this soon.
  • Privacy-preserving compliance: ZK proof verifications and a reputation-based score keep users verified yet private.

“People shouldn’t have to choose between convenience and control for investing into coins,” said a P2P.me spokesperson. “Coins.me makes entering the crypto world feel intuitive and familiar without giving up on any of the principles of decentralization that make it valuable.”

Built for the Next Hundred Million

Decentralized apps often lose mainstream users to complexity. Coins.me flips that by focusing on high-velocity payments markets and abstracting private keys, gas, and bridging. Transactions settle on Base for transparency and auditability while users get a fintech-grade interface. It’s also a natural stablecoin gateway to crypto adoption, letting users in emerging markets hold or transfer USDC and buying other top cryptocurrencies, without the need of centralized exchanges.

“Built on Base, the open protocol plans to launch a token to shift control to the community,” CoinDesk reported earlier this year, noting P2P.me’s path toward user and LP-led governance and upcoming TGE / token launch.

Beyond a Wallet

Coins.me combines smart contract wallets, gas sponsorship, and privacy-preserving verification—a blueprint for the next wave of Web3 consumer apps. Custody and private keys remain with the user while the experience rivals traditional finance.

By keeping custody and private keys entirely in the user’s control while offering an experience comparable to traditional financial apps, P2P.me is signaling that decentralization and usability can finally coexist.

Industry observers have framed P2P.me as “a decentralized platform for fully on-chain fiat swaps with zero-knowledge KYC and DAO governance to combat fraud.” Coins.me now carries that philosophy to the end-user.

What’s Next

Coins.me is live globally for swaps, with ramps currently in India, Indonesia, and Brazil. Road-map items include a governance token, expanded fiat rails across Africa, Asia, and Latin America, and tighter integrations.

The ambition is clear: make crypto useful for anyone, anywhere—without forcing them to learn its complexities—while staying true to decentralization and privacy. With a gas-free interface, instant local payments, and self-custodial security, Coins.me shows what a user-first Web3 experience can look like.

P2P.me is also planning for a TGE for their token launch by March 2026, where a discounted token sale pre-TGE will occur for users with completed ZK verifications and executed orders on the P2P protocol.

For millions already fluent in digital payments, Coins.me may be the easiest path into crypto. For P2P.me, it’s the culmination of a two-year push to make decentralization practical, fast, and human—redefining “on-chain” as a normal part of everyday life.

Preliminary analysis of the Balancer V2 attack, which resulted in a loss of $120 million.

Preliminary analysis of the Balancer V2 attack, which resulted in a loss of $120 million.

On November 3, the Balancer V2 protocol and its fork projects were attacked on multiple chains, resulting in a serious loss of more than $120 million. BlockSec issued an early warning at the first opportunity [1] and gave a preliminary analysis conclusion [2]. This was a highly complex attack. Our preliminary analysis showed that the root cause was that the attacker manipulated the invariant, thereby distorting the calculation of the price of BPT (Balancer Pool Token) -- that is, the LP token of Balancer Pool -- so that it could profit in a stable pool through a batchSwap operation. Background Information 1. Scaling and Rounding To standardize the decimal places of different tokens, the Balancer contract will: upscale: Upscales the balance and amount to a uniform internal precision before performing the calculation; downscale: Reduces the result to its original precision and performs directional rounding (e.g., inputs are usually rounded up to ensure the pool is not under-filled; output paths are often truncated downwards). Conclusion: Within the same transaction, the asymmetrical rounding direction used in different stages can lead to a systematic slight deviation when executed repeatedly in very small steps. 2. Prices of D and BPT The Balancer V2 protocol’s Composable Stable Pool[3] and the fork protocol were affected by this attack. Stable Pool is used for assets that are expected to maintain a close 1:1 exchange ratio (or be exchanged at a known exchange rate), allowing large exchanges without causing significant price shocks, thereby greatly improving the efficiency of capital utilization between similar or related assets. The pool uses the Stable Math (a Curve-based StableSwap model), where the invariant D represents the pool's "virtual total value". The approximate price of BPT (Pool's LP Token) is: The formula above shows that if D is made smaller on paper (even if no funds are actually withdrawn), the price of BPT will be cheaper. BTP represents the pool share and is used to calculate how many pool reserves can be obtained when withdrawing liquidity. Therefore, if an attacker can obtain more BPT, they can profit when withdrawing liquidity. Attack Analysis Taking an attack transaction on Arbitrum as an example, the batchSwap operation can be divided into three stages: Phase 1: The attacker redeems BPT for the underlying asset to precisely adjust the balance of one of the tokens (cbETH) to a critical point (amount = 9) for rounding. This step sets the stage for the precision loss in the next phase. Phase Two: The attacker uses a carefully crafted quantity (= 8) to swap between another underlying asset (wstETH) and cbETH. Due to rounding down when scaling the token quantity, the calculated Δx is slightly smaller (from 8.918 to 8), causing Δy to be underestimated and the invariant D (derived from Curve's StableSwap model) to be smaller. Since BPT price = D / totalSupply, the BPT price is artificially suppressed. Phase 3: The attackers reverse-swap the underlying assets back to BPT, restoring the balance within the pool while profiting from the depressed price of BPT—acquiring more BPT tokens. Finally, the attacker used another profitable transaction to withdraw liquidity, thereby using the extra BPT to acquire other underlying assets (cbETH and wstETH) in the Pool and thus profit.
